N.B.
J., sorry to hear this - I am now 43 - married 18 years - and my husband has left me yet again the 2nd time - this time he has been gone for 2 years - but has not divorced me - yes there were other affairs - but this may not be what is happening w/you.
I too - when we first married and had our daughter - he worked all the time - and our relationship grew apart. I thought - ok i take care of the kids - and when they get older - then it will be our time - well my daughter is 16 and my son is 10 - he has spent his days off w/others and not us.
My feeling is that you do need to get help w/this - or you won't have any kind of relationship. Mine went on for 16 years - and look where I'm at now - in my prime - yet still lonely. All the pictures i have taken are w/family - but he was never w/us. Even w/his older daughter who is now 25.
Its a selfish thing - your husband is being selfish - and if he does not catch this now - it will get worse - that is my opinion - I always heard i was no fun anymore - but it was b/c i now had to be responsible for a child - i'm not going to go out and party - most mom's do this - they take on the parent role while the husband still goes out and does his thing. Again, you need to get some counseling. I don't know if you are religious or not - but I am now a Christian - was raised Catholic - but really didn't learn too much except ceremonial things. But GODs word tells us that a husband should treat his wife like God treats His church. And the wife should love her husband and submit to him. But God doesn't mean for us to be walked on - HE created a woman for Adam to be his helper - and for him to lover her for God chose woman which was the best fit for man. I pray for you and your family - don't let years go by w/out addressing this. You can still have a beautiful relationship - but it is a different one w/children.
God Bless
