love suck... not always...

okay I'm only 13....too young for a relationship...but seriously...? like 2/3 days ago I got together with a girl and it was great except that he probably just wants to use me to do things...yes..that things because he says he already wants to do things with me but we've only been together for 3 days... like more than two hours ago I was talking to a friend of mine about my new girlfriend and I sent her some screenshots of the chat with my "girlfriend"....she says that is a toxic relationship and since she has already experienced this type of relationship she know what does it mean she says that my girlfriend, as soon as she has the chance to touch me, could do anything...she's a lesbian too so I think she understands me well...what do you think guys? I don't know what to do...do I have ideas conditioned by others? Am I wrong? Is it the others? Should I leave this girl? Should I listen to my friend and walk away from my "girlfriend"?  Do I do things my own way? What if it ends badly and I fall back into depression? I don't know and then like an hour ago i met this guy and he seems great.. because he is literally the kind of partner i want.. the problem is too good to be true....I don't know what I feel inside...I'm not feeling very well mentally at the moment I don't know if I really love her after the messages from this friend of mine...and analyzing those of my "girlfriend" people take advantage of me..and I can't take it anymore.. I just want to have a person to cuddle with, kiss and be together...I think that  I'm too stupid in love...
