Forum : Pregnancy

Me and my partner split soon after he found out i was pregnant and said that we would both still be parents but he cant see us working.
He then told me 6 weeks after this that he was starting out with someone new and things where serious i couldnt understand why he thought he needed to tell me this as we only spoke about our child nothing else... but i decided to keep my distance and allow him to contact me when he wanted to know something.
I am now 27 weeks pregnant and have seen him a few times. but was a friends birthday on thursday and we decided we was going out for it(friends and me). I aint very big at the moment just starting to get a little pot belly but seem to be losing weight everwhere else apart from my boobs.
To my suprise on thursday he was also out with one of his friends but he came jogging up to me in the que and slung his arms around me and attempted giving me a kiss. commenting how good i looked and that i was losing weight but getting a little belly and his words where i love it ... i was stood there not sure what to do then he was stood chatting to me and my friends but wouldnt leave we then went into the club and he was watching everything i did asking if i was wanting a drink!
He then introduced me to a couple of people who i have never meet who started saying they heard lots about me and that i am going to be good we are together...??
Then in the next breath he was speaking to one of my friends saying how he cant wait until our son is born as he is going to be there constantly and he thinks he might aswell come in now as when babies born neither of us will be going out he then went on to say how he was going to get rid of the motorbike and do his car test but wouldnt need to buy a car as we could share mine and how we should decorate my living room brown and telling my friends where going to be great as a family.
This all confussed me and when we moved to the next place him and his friend nick decided to follow us up to the next bar. then i recieved a phone call off him arund about 3 am asking i wanted him to come up to mine and spend the night and that he thinks its a good idea, that he misses me.
I told him i wanted to go to sleep and would prefer him not to call and said i would see him around but the first thing that crossed my mind was about him been in a 'serious relationship' now so why was he calling me.

I've spoken to some people about it and they believe it might be he thought i would be big and fat and waiting about at home for him to come back... and a friend told me he isnt in a relationship with anyone... so has he said it to get a reaction which i didnt really give just said i hope it goes well for him....
What do you people think is going on i cant understand him and i just need some opinions on the whole situation
