What should i do?

Me and my bestfriend has been cool for 7 1/2 years.We have done everything together and since i introduced her to my bf she don't want to hang with me any more it seems like every time he comes around she always gotta touch him.We have been datin for 2 years 5 months 14 days 9 hours 43 minutes and 3, 4, 5, 6 seconds.I love him with all my heart because of the simple fact when we first got 2 gether i was 3 months pregnant and did't tell him until i was 6 months.Even though i lied to him he still stuck beside me through everything. And he is being a father to my child even though it ain't he's.He does everything for me.He cried tellin me he love u looking in my eyes.He is my everything but when my bf is around he pays no attention to me and my child hes attention is basicly on her.I try to tell myself that they r just friends and it's not workin.I love him but that b**** will get cut over my man.She slept with my daughters dad and i forgave her but with him, i don't know what im gone do.
