<human>: Can you give me a shortened version of the text?

This is probably going to end up being a wall of text, so here goes...

About 6 years ago I broke up with my ex (27m), it was a bad break up, and we had to go to court to settle our custody arrangements. Our custody agreement he's constantly breaking, trying to pick her up from school when I'm not around and not asking me for permission etc etc.

He is the kind of person where if you say no, he says f+++ you and just does it anyway. He puts himself in our lives when he is NOT welcome. He shows up to our daughters' soccer games or swimming lessons and tries to get her to go over to him, hes' tried to take her from those events as well. Once he tried to grab her from my sisters arms, I knocked his hand away and he tried to charge me with assault.

Anything he CAN do to mess with my life, he will. I see him out wandering at kids events looking for us. He went to my sisters work to ask for photos of me for a "present collage" at Xmas. He tells our daughter on his weeks, that we're going to get back together and its affecting my current relationship. 

My bf (23m) is great. He's been calm and as understanding as possible but I feel like my ex is really starting to mess with us. We've been together for 5 years now, almost my daughters whole life. But my daughter always brings up in front of him stuff about how her dad is gunna buy me gifts and how he wants me back and how my daughter wants me to come over to his place. Its starting to make me very uncomfortable. I don't want to lose my man because he thinks I'm sneaking around with my ex -- which would never EVER happen. I am hoping someone here can give me any advice or can talk me through this.
<bot>: my ex is telling my daughter we're going to be a family again and my bf and I are upset about it, it is affecting our relationship. HELP
