Does this guy like me?

I've been talking to this guy from a really long time..and he's fun and I kinda like him...soo yesterday I was talking to him and he sent me a message saying "I love u! <3 mwah..wish u were my gf. U rock! :(". V usually say I lov u to each other cuz well..I considered him as a best frnd..and thn later on he msgd me 'I wana hug u' I don't no if I can trust him or not cuz he has a lotta other random gurls on fb :\ sooo wat do u guys think? Is he playing? And plus he's my ex boyfrnds frnd too..nd once wen I was rly ngry on my ex .. He told me tht ' I can take ur revenge ..just tell me wat to do'. So thn I just told him to leave it..I really lov this guy..but I'm scared to tell him cuz I got dumped b4 by my boyfrnds..so I think this guy wud do da same.! How can I keep him attracted towards me and how can I no tht he rly loves me..
