Love triangle

I have a boyfriend we've been together for almost 4 months but lately my boyfriend hasn't given me a time and attention I want I know he has personal problems he's going through but it's really hindering our relationship and lately I've been talking to my middle school crush happy I mean morning afternoon all the time and I think we're both starting to like each other he's even gives me butterflies and I honestly don't know what to do And me and my middle school crush don't do anything if I have conversations over the phone he lives three hours away from
