OP, I think you just have to accept that once they're in different kind of relationship, as in in love with someone, that's a far deeper connection and it will take precedence.
Life changes, priorities and people change and if you try and cling on to "friendships" with married men as if nothing has changed, you will look a bit desperate and a loon. Sorry to be harsh, but this is reality in most cases.
I wholeheartedly agree. And I think if you're a single women who wants to stay close friends with a male friend, (and socialise with him ALONE,) when he has found another woman he is physically attracted to, and deeply in love with, and got married to, then you DO come across as rather desperate.
He has found someone he likes more than you now. Do the decent thing and move on. Say 'hi' when you see him, and mix socially with him and others - including his wife - but if you need to socialise with him ALONE, (when he is married,) and you feel you are ENTITLED to, then that is a special kind of weird and desperate.
And as I said earlier, it's a bit odd when these 'single females' want to stay bezzies with their male friend (after he has got married,) and they don't want to KNOW his new wife.
As g1illterati said, you gotta be some special kind of dumb to think the friendship will stay the same, when your 'male friend' meets a woman he likes more than you, and gets married to her.
