<human>: Can you succinctly summarize the text in 1-3 sentences?

So I've [21F] been with my [23M] boyfriend for two years and a half now and he recently left to go to another state for about six months and while he's been away he's been very distant, so I started making my life as normal as I could without him being around and I ran into an old friend [21M] and we've been hanging out a lot lately because we have a lot of fun together, we're basically the same person; but I just found out he's in love with me and since then I'm getting these mixed feelings because I think I care about him more than I should, I might actually be falling for him, but my bf is coming back soon and I don't know what to do... 
Any advice?
<bot>: my boyfriend has been gone for a while and he's coming back but I think I'm fell for someone else while he was away. Advice please!
