<human>: Condense the text into a few key points

I recently moved to university, roughly about three months ago.  I met two people who already knew each other and instantly became friends with them both. Me and then lad got on really well, we are very similar people. By the third day I developed feelings for the girl and she did for me. We started seeing each other a lot, near enough every day. I still saw the lad as we were becoming good mates. For my birthday us three went out, and all got really drunk. The girl got upset because she couldn't find me as I was in the smoking area for about an hour. She got worried and ended up having to go home, with the lad. The lad tried to get with her but she denied and pushed him away. 

When I found out the next day I was angry, obviously. I was the bigger man however and I talked it out to the lad and gave him a second chance. Two months later and me and the girl are really close, but so are me and the lad. It turns out that the lads ex is the girls best friend. So this creates drama every now and then. A lot has happened recently, and I used him as a vent if anything went wrong with me and the girl. 

Yesterday he gave me an ultimatum and is making me choose. I walked off and rang the girl as she is really helpful. She told me that if he is acting this childish then it's a difficult one. I agreed and we came to the conclusion that we would stop seeing each other but resume in a few months. 

I told the lad this and he didn't take it well, he's asked me to think about it more and come to a conclusion. He stated that he could still be my friend but not as close as he was because he sees me getting and it reminds him of his ex and he doesn't want drama. As a lot happened over the past week, she hurt me a lot but I decided to give it another chance with her, as we both feel strongly towards each other. 

I can't decide. I just hope that siding with the girl isn't the wrong choice.
<bot>: met girl and friend at same time. Love them both (in different ways) and now my friend has given me an ultimatum.
