Ok so for those who hadn't read my last thread about trying to get my ex to do 50/50 basically we were buying a house together, 2 days before the sign date he said he didn't love me anymore and just left (he works away so just went there). I was very heartbroken (this was 6 weeks ago now), but tried to just get on with life without him. 5 out of the 6 weekends he came to get our daughter we had sex, but he left after each time and I just felt used.
Fastward to last week and he agreed to 50/50. Meaning looking for a new job here and moving back. So on the Friday we agreed to get a drink and discuss the arrangements on what would work best... ended up getting completely drunk. He cried in the bar about how rubbish his life was 
and so on. I held back on comforting him, because after all this guy has practically ignored me for the past month and broke my heart. We moved on to another bar and literally danced the night away. He had never seen this version of me (I actually don't drink normally, but my friends have been getting me out of the house). We were dancing together, having dance off with other people, and just generally having a good time. He then came back to mine, and I just put him on my sofa in my room.
In the morning our daughter came in and seemed a bit wary like who the hecks on the sofa haha, so i went other to him and asked him to either get up or go get into bed, he said are you getting in it too? I did and we just cuddled 
. Fell back to sleep and his alarm went off, he didn't wake up so I got up to turn it off and noticed he had a message of a girl I always had doubts about. I made a sarcy comment whilst tossing his phone on to the bed like 'oh yea btw your whores text you' 
He got up we had a little argument he did the I knew i shouldn't have come (What I expected him to say as that what he said after each time). He went in to the bathroom and came back half hour later and just got into bed cuddled me and said 'you're such a plum' .
I assumed he would then take our daughter back to his for the rest of the weekend but he didn't. He just stayed and didn't even mention leaving, we just acted like a family, went out for lunch etc and that night him and I got a Chinese.
So on the Sunday i told him I had sorted all his things out. Amongst everything was a whole load of photos and an embarrassing memory book of us I had made. I suggested we just got rid, but he got very defensive saying no he wanted to keep them because it is memories.
So before he left I thought I would bring up the why don't we work this out speech and got shut down and told he needs time.
Then on the way home he sent me a text about a car and used the word 'us'.
The Monday he just ignored me as I poured my heart out. And the Tuesday I was where he works and asked if he would like to see our daughter and he said yes. Once he left he text me saying 'sorry'. I replied with ' I know you want to work it out, you would say otherwise.'
He said 'Im just so confused'
We are supposed to be going to a music festival together tomorrow till Sunday and he's very adamant we still go together but that it won't be good for me? Do I go with him as a 'friend' and show him how fun I really am in hope that he misses that or should I just give up and stop playing these games?
- He also ordered 'a little bag of happiness' from notonthehighstreet.com On the Saturday he was with me. I noticed it in the emails, probably stupid to hope it's for me.
