I need help with this relationship?

I have an amazing boyfriend named Tequan. We have been together for 9 months,at first he was super sweet and amazing. Over time he has become an *** wipe! I have a really good guy friend in Washington my home state, named Antoine. I really like him and I am pretty sure we both love each other. My boyfriend Tequan (we willl call him T for short) found out I was talking to Antoine( I call him Tyson for short, becuase thats his middle name) and he was very mad at me. He banned me from talking to him, he was cheesed off!!!! I love Tyson but me and T really have a good relationship. I have known Tyson for 5 years now and I know I want to be with him forever!!! We are true soulmates!!! I just love that I have found him. But T thinks that him and I will last forever, sadly I cant stand him much longer. I dont know what to do because me and Tyson only see each other once a year at most. When I turn 18 I plan on moving in with him but unitl then I am not sure what to do!!!! Please help me!!!!!!!!???????????
