Does he love me as much as I love him

hi, my boifriend and i have been going out for a year now, the first time i saw him was at a friends howse. i inmediatly loved him. after that night i saw him three months after at the same friends howse, they were both friends. i made a move and told him i liked him and we started to go out. my problem is that i feel insecure , jelous,doubtfull and sad most of the time because i think he does not like me as much as i do. i adore him! The reason i feel insecure is because i asked him out he dint.. that makes me think that he may have never asked me out if i hadnt... i feel jelous because i think he likes my friend, he talks abot her like if he knows her very well and comparing that to me it seems he knows me very little. she is also very funny and i know she likes him.i feel doubtfull because he did say he does not like her but when she is arround he gives her full attention, not only that he also looks happyier. he gets exited when she is comming, and they stick together when i get drunk and smak my head and bleed. so yes i feel sad because i am in love with him and dont feel the same back from him even if hedoes tell me that he does. thanks for reading. luz
