What should i do im so confused?

I have known this guy for 16 years been bestfriends with him for a while now,. Whaen we first started to hang out it was just as friends, but lately i have more feelings.. i have told him bout my feelings and his reply was he loves me but not inlove with me.. so i left it at that although admittedly was a lil disappointed. However a few weeks ago he done something nasty while he was drunk and i found out the wrong way. i was so angry that i didnt want to speak to him or look at him, he came straight to my house and explained what happened coz he said he doesnt want to lose me and that im the only person that actually cares about him. he has never been inlove before, and has never had a girlfriend. After we worked through what happened since then he has invited me to his house pretty much everyday, he cuddles me, he kisses me, i always joke to him that me and him will get married oneday and he goes along wit it. but yet he is still saying he isnt inlove with me.. what do i do?? i dont want to lose our friendship as it is so strong, but im inlove with this guy i just wished he felt the same. my mum believes he is too scared to admit it to himself that he does love me coz its all new to him, but i dont want to get my hopes up. also when we had that fight he cried and said later that he very rarely cries and that must show how much i mean to him. Im so confused, help...
