Thanks @pickledandpuzzled .
I was a little miffed but only a little, when I got there anyway after seeing my other friend in the morning, because we were meant to be going out for food, have a look around town, some drinks but somewhere in the interim period after it was arranged for me to visit, she had decided that we weren't going out now, she didn't want to bump into her colleagues (not direct colleagues) who were out at their xmas 'do'. I dont know why.
So they just wanted to sit in the house all day drinking then order food later and again, that isn't my idea of fun, I don't like daytime drinking and I find it quite boring but I played along and we had some nice chats, watched some series we all like.
Then that happened with her getting very drunk and me being upset.
Perhaps not a great idea anyway because they got together not long before me and DP did although I have known both of them much longer, and it just feels a bit upsetting that they're living together, discussing marriage and happy and I got what I did with DP, I didn't get that happy ending.
Maybe I do put my needs last, you may be right-I certainly have sacrificed a lot of them in this relationship.
I feel I dont know where to start with putting my needs first really! I dont even know what they are any more.
I am especially upset today because DP was meant to come over today for the whole Xmas period. 
I have been quite shaken, not been able to eat and had an upset stomach.
Of female friend who upset me, I have spoken to my Mum about her who has now told me she suspects she doesn't actually like me.
When they got together, she became quite jealous of mine and her DP's friendship, although I have known them both similar lengths of time, I was closer to him.
Back then I had to go to lengths to explain to her that I wasn't a threat, at all, I wasn't interested in men, he was like a brother to me, we didn't have anything more than friendship at all. She had some huge arguments with him about me, one memorable one was when I was at a mutual friend's and I knew they were at a show nearby, and mutual friend said 'Why don't you ask X and Y to come over too?' So I rang him and asked and I heard her start screaming at him. Because I had called.
She had been cheated on by her exDH not long after they married so I understand to an extent, but it wasn't a nice time for any of us.
She did calm eventually and I felt we were all good again now, but my Mum thinks perhaps she took a thrill in seeing me upset and vulnerable. She kept trying to cuddle up to me and I just didn't like it, just wanted her to drop the whole thing
