Did your child sleep in your room in the begining? Just curious if maybe this was a trigger to his sleeping on the couch. My kids have all slept with me and while it did not chase my H out of the room it did annoy him. S10 and S13 still climb in bed with me on the nights H is not home.
Do you and your H have a social life. Hobbies friends to just pal around with. Just wondering if I am bored is becoming I am not in love with you. I read alot on the walk away spouse boards and the MLC boards alot of the people there all to seem to have something in common they had no life until the spouse went off or said ILYBANILWY line I want more then this. Then they made a effort GAL do a 180 the whole nine yards. A little to late for some. So boredom seems to play a large part in some peoples problems. So just wondering if by chance that may be where your H stands just bored more then anything.
Also you said that you have told him repeatedly how you feel. That seems to be common one person talks while the other is not really listening. Or does not seem to get what the other is saying. BTDT but some people seem to find a way to finally get there message across. So keep trying.
The phone thing. Well it is a indicator IMO that not only are you not satisfied with your sex life neither is your H. Does he ever come to you for sex or do you have to always be the one to start things? While I cannot say it is right or wronge in your relationship IMO it can become a larger issue if it continues. What is satisfying him now to just say may later become a satifaction by act instead. I would say keep your eyes open wide on that.
There are many great people here you will get lots of feedback just keep talking even that helps. To know you are not alone is awesome help in itself even if it does not change the sitch.
