so this girl and I have a thing at the moment and I want to ask her out. but I have a friend coming in from Venezuela that wants to fwb for 3 weeks this summer. I think the girl I have a thing with could last a long time. but I don't want to ask her out because I don't want to one day cheat on her. what should I do? I want to date her and have fun this summer but I don't know. please help me make the right decision and also know I'm not some asshole I just really like both girls.

fwb=friends with benefits

it's like hooking up with no attachments

I'm 15
