<human>: Basically me (21female) and my ex (22male) had been dating approx 2 months before he decided he didn't want to be with me anymore because he was moving away for university and despite knowing how upset I was about it still didn't care and went on with his decision. 

I started back at uni this September and ended up very close with one of his mates (21male) just as friends at first but ended up spending all of our time together and ended up falling for each other. Once we got together I found out my ex had slpet with someone else but couldn't care less as I had someone much better and was much happier. 

Anyway we ended up telling him and my ex went crazy at my current boyfriend calling him for all sorts of names, mentioning the stuff me and him had done together etc. Then turned round and said he never wanted to lose me and that he was still in love with me

Me and my boyfriend are still happily together and defiantly a much better match for each other than me and my ex ever were. But now my ex is back from uni and has contacted my boyfriend to ask t ogo for a drink

Can you condense the text into three sentences or less?
<bot>: should my boyfriend go? im extremely worried as my ex is very sly and I don't want him to try and mess things up
