I'm 17. The thing is, I love a girl, who is my best friend, let her name be D. I think D too loves me. Just yesterday, another girl came and proposed me, let her name be P. I know that I don't love P. I'm trying hard to convince P, but, she's not understanding. P is telling that she loves only me and can't think of anyone else. P is telling that if she marries anyone, it will be only me. If I decline her proposal, she is telling that she will remain single for her entire life. I don't want P's life to be spoilt just because of me. I love my best friend, D and I'm sure that D too loves me. How should I make P understand about this? I don't want her life to be spoilt just because of me, also, I don't want to lose my best friend, D's love. Please help me get out of this situation.
