In answer to your question, if he really does love you, why would he be treating you this way? He should WANT to be with you and from what you described, a lot like MY husband, he doesn't seem to want that. Counseling MAY help. Try to encourage that.
My husband and I have had a long-term relationship, off and on. He cheated on me with several women, finally leaving me for one of them only to be dumped by her 3 times, this was while we were dating then engaged. Several years later, I gave him another chance and we did get married. 3 years into the marriage it seems that he's back to his old ways again. He kept in touch w/one of his women, he's tried to cheat on me many times, even found out that while he was on out of town job training, he'd tried to pick up women! Even the neighbor's ex until we moved out of that area! Even after we moved, he found the neighbor's ex on Facebook and messaged her several times.
It's now been 13 years that we've been married and he's now purposefully doing/saying anything he can to try & piss me off so badly that I'll leave so he can be w/a woman he had a crush on in high school. He wants me to be the 'bad guy' this time, apparently, making others think that 'he' is the victim. I found out that he's been emailing, texting and calling this new woman for 7 years now! Making plans to be with her, even going so far as to try & talk her into moving here! (She lives out of state). He even makes plans to be w/her if I have to go out of town, even telling her he wanted to take her to their high school reunion instead of me! He also purposefully starts arguments w/me just to get me riled. No reason for that, he just blames me for his unhappiness. I've done nothing but be fully supportive & to be encouraging of him and of his interests & endeavors. I've tried to find things for us to do to spend time together to no avail. He simply does not want to do anything w/me. When I DO get him out of the house, he acts pissed off, like he don't wanna be there, spending most of the time on the phone texting or playing games or on Facebook. I'd rather go out by myself now rather than tiptoe on eggshells just to be with him. He takes forever to get things done around the house. I've spent so much money on upgrading the house. He didn't want to but it REALLY needed help! He bought us a fixer-upper that was way too small so it's taking a long time to go through everything and downsize but doesn't seem at all appreciative of my efforts.
He started doing things like moving my hand away when I try to cuddle on the couch, etc. or he'd move away when I try to cuddle or be intimate or even try to hold his hand, he'd take his hand away from me! Even walking down the sidewalk or in the store he doesn't like holding my hand anymore. He's started sleeping on the couch now, his choice...not mine but yet he makes it out like I forced him out of the bedroom, not true! He even tells his women such awful, made up stuff about me, even telling these other women extremely private things about me that is NO one's business! And yes, I have proof he's done this.
He doesn't appreciate anything I do for him, at all. He doesn't thank me for doing things for him he barely mumbles out a "thanks" but he says in a smirking kind of way if he does thank me, never sincere, even though I do thank him for helping me, doing dishes, etc. Another thing I've noticed is although I do give him his gift, for 3 years he hasn't given me a gift for my birthday, Christmas or anniversary, not even a card. I know that's not realllly all that important but it's nice to be remembered and thought of on those days. He says "oh, I forgot" but never gets me anything afterward, not even a card. When he does get me something, it's just some small, cheap item that's as though he ran into the store and grabbed something real quick, like a USB card or something like that, that I don't really need, nothing well-thought out or sincere while I spend a lot of money and effort in getting him something he wants/likes then doesn't even use it after mentioning it over & over that he wanted this or that. He also says he'd rather work than spend the holiday w/me or even works on our anniversary now. I don't know what to think anymore.
I would leave but unfortunately, I've had a multitude of job losses due to disability so I don't have any means of fully supporting myself at this time so it's difficult for me to leave right now. I've always been taught, and believe, that marriage is forever but I've had just about enough of his behavior but I'm not in a position where I can leave. It's really tough! We're also due an inheritance from the in-laws so IMO, he's trying to get me to leave before that happens so he'll get the full amount rather than giving me half. I'm determined to get my share so I will have something to live off of and won't have to worry as much. I know that probably sounds selfish of me but I'm not in a position that I can support myself due to a current disability. I too, am wondering what I should do. I thought we were perfect for each other b/c we have so much in common but I am so tired of his pissy attitude, especially when he points the finger at me rather than explaining what it is exactly that I've done wrong.
I would definitely encourage counseling, if he still refuses, why not just come right out and just ask, point blank...honey, DO you want to be with me? Because....then bring up the things that you mentioned. Listen to what he has to say. If nothing gets better, tell him that counseling may be a way to get through what's wrong in the relationship. If still no change, try a legal separation and see if that helps. Sometimes people just grow apart but I'd start w/counseling.
