<human>: Basically my ex and I dated for 5 months. He was my first somewhat serious relationship. He was also my first everything. He cheated and to top it off he broke up with me. He'd also ask me out on dates after only to let me down and say he was kidding in the end.

Anyway he and I have been split up for a while now (8 months) and during the time we had been broken up hes kept in contact with me even though i had asked him to stop he had also asked us to meet as well as bought me some gifts. WHILE HE HAD HAD A GIRLFRIEND. 

So I had been working out and started talking to an old friend who was pretty fit and he asked me to go to the gym with him. So I did and posted a status praising this new guy. My ex, emailed me saying that his new guy was a loser and didn't know anything about working out. He also pointed out things that the new guy and I had said in convos on some posts. 

Also my ex had been confronting me about some posts and pcitures where I had been going out and drinking. (holiday season why not) 

Basically most of the messages said things like

oh you never drink why you start now

why are u out drinkin if you never did

i miss u n u ignore me

shit along those lines. I've basically just ignored all his comments and kept living my life.

Here's my thing:

I feel like I'm somewhat over my ex ( I was really in love) I like going out and meeting new guys but a part of me misses him and finds it hard to let go even though he already has.

I like the new guy but I feel like he'll be a fling or maybe just a friend.

Can you summarize the given text in a few sentences?
<bot>: Ex seems jealous has had crazy behaviour; part of me can't let go but the other half wants to find a new person to be with.
