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

I [20F] and my current SO [22M] have been dating for around a year and three months so far, and we've had a lot of ups and downs, but currently we're doing pretty good in terms of our happiness as a couple.

However, I can't seem to shake my feelings for my ex [21M]. We broke up around October of 2011 due to him leaving for boot camp for the marines and not really feeling sure on where our relationship was going (we'd been dating around 8 months). We both still have strong feelings for each other though, and just trying to ignore those feelings doesn't really help.

I'm one of his closest friends, thus simply not talking for an undetermined amount of time (in an attempt to have the feelings leave, or at least lessen) isn't exactly a good option.

I've also noticed that, for periods of time when my ex and I don't talk, the feelings aren't as noticeable, and I'm even happier with my current SO. But the second my ex and I start talking again, the feelings come rushing back, especially since he makes it clear he'd prefer for me to break up with my SO and date him instead. He's content staying friends if that's what I want, but he knows I'm not over him, and thus keeps throwing the idea out in the open.

I have no clue what I should do, and I'm fed up of feeling torn. I've been this way for months, and it's not fair to either my boyfriend or my ex to keep almost leading them on this way. Please help?
<bot>: – Can't choose whether to leave my SO for my ex or stay with SO and ignore feelings for ex till they go away. Advice is extremely welcome.
