Me 8 months on, dark and trying to detach.

Btw you seem to really resent the fact you were not invited to FIL party or your W's family not contacting you for 8 months. Did you at least send a card to wish him happy birthday?

Forget about what your W or your in laws have or have not been doing for you and focus on you just like how a lot of people have suggested. They have their lives just like you have. If you are a loving caring person your W or anyone would love to be around, what would you do if the birthday of your FIL you care about is coming up? You would simply wish him a happy birthday, and that's it. It shouldn't matter if they invite you or not.
I know it hurts and it would hurt me too but if you guys continue doing things when you guys did when you were together, that's not a "separation" don't you think?

I used to be like that from time to time. When my MIL didn't contact me after I did something nice, I would start feeling slight resentment. It always turned out she was way busy or had gotten sick or something like that. I mean I have a series of emails I need to reply to but I haven't gotten to them because I just have my hands full with my situation. They have their lives. Only because they haven't contacted you, it doesn't mean they don't think about you.

Just a thought
