Not sure where to post this...

This doesn't have anything to do with a period or sex or anything I just really need advice... I've been talking with this guy for almost 2 months and we've had sex a few times and talk 24/7 over text or on the phone and we see each other often... I told myself I wouldn't do this but I think I'm falling in love with him and I don't know what to do... I know he likes me cause he's told me before but I don't know how strong his feelings are and if I tell him I'm falling for him i might lose him and I'm scared... What do I do?
