Most Helpful Girl
Lots of eye contact, smiling, initiating conversation, he will try to help you out in any way, and will just seem to perk up when you're around. Texting is a hit and miss, dont base it off of that. Some guys text a lot, others don't even look twice at their phone. If they're friends ask or joke around about it sometimes, and i guess if they like you they will eventually ask to hang out or something.
The guy i like is quite shy and inexperienced like me, but he's done all of that and offers to drive me home every week. He doesn't really text me, but he's asked to hang out sometime soon, and i mean this has been going on for like 4 months.
