Hi J.,
I think I can sort of relate to what you are going through. Before I married my husband in March 2006, we had been dating for about 4 years and I have a 10 year old daughter. He moved us out here from Hawaii for his job last July with the knowledge that I have no family or friends here so we are pretty much on our own. Well, last year in the later part of the year we were fighting quite a bit and he would yell that we should move out as well, and I thought that was really horrible (what a jerk)! And I was thinking do I really want to marry this person, but we would eventually calm down and talk about what the real issue(s) and it really helped and we both agreed that leaving my daughter out of our fights was best for her and we still think that.
When I got divorced from my first husband, before I left I constantly reassured our daughter that it had nothing to do with her and that both he and I loved her very much, and I would just keep saying that and the teachers in her school noticed that when I was with my ex her school work was having trouble b/c we were fighting so much but after we moved out it actually improved. I am not saying this will be the case for you but what I am saying and other Dr.'s have said this that never put your child in between and try to reassure them that it is NOT their fault at all. This is in case you should decide to leave.
When some men say "Leave" they can mean so many different things - my husband means - you are hurting me so stop it or I/you have to get away, some may mean I have things going on and don't want to disappoint you so go away, I am just saying it may not mean for you to actually "Leave", you have to talk to him and ask him what's really going on.
If you ever want to talk here is my number, I would like to make new friends here if I can and what better way than to commiserate sometimes. ###-###-####.
Take care,
C.
