Regarding married friends and "3rd Wheel Syndrome":
Don't question their motivations. Don't assume you are an imposition. Accept their hospitality when it is offered, if it is helpful to you, and decline politely when you feel like wallowing at home alone.
They are your friends, and yes, maybe they are trying to help. Let them! If you turn away, you will grow apart. This is how friends are lost, and why it seems like you divorce a whole social set instead of just your S.
There are enough 'friends' out there who are too uncomfortable to call or don't want to take sides or whatever. Don't let go of the ones who care enough to make an effort, just because you feel like you're imposing. That's what friends are for!
