I have found that the friends I used to have stopped calling when I moved in with my partner. Maybe because they were no longer my 'number one' friend anymore, but like I care.
I have found that friends who lose touch, don't call, and just don't care anymore, aren't worth it, no matter how much you thought they were friends.
I am happy with my partner, we sit at home on weekends just doing 'stuff'. We occasionally go out wirh work mates, but all the friends we used to have (we both have the same circle of friends and used to go from party to party each week) have just stopped inviting us anywhere, or including us in anything. There are still a few who don't call, but if we see them or something, they say hello and enjoy a catch up chat, others just don't care or make comments about us and if we are happy being 'a married couple'
I gained a best friend and lost a **** load of fake friends. No biggy
