Problems 😧💔

So I've been in a relationship with this guy and he tells me he loves me but he's unsure about our relationship (we go to different schools and see each other like once a month sometimes every 2 months) and idk what to do especially since we decided to tell each other things we've kept to ourselves and just put it in the past and move on I told him I had small crushes on a couple guys BUT THEY DIDNT MATTER bc I wanted to be with him and they were all just like rebound feelings BC I missed him so much and he tells me he flirts with his friends sister and he "doesn't really flirt anymore" because she "became an overly attached friend" and he gives her freaking piggy back rides and let's her hug him and my friends are telling me if he's giving her piggy back rides flirting and hugging her and said what he said about her being overly attached then they might've done something a little more than just hugging like they could've kissed or maybe something even more......😖
