There is someone whom I consider a best friend, whom I have been with in the past, but never dated before. He has been in love with me for six years now and always 100% treats me like I'm a princess, and is always kind and perfect. For some reason I have never really given him a chance. Its like I don't know how to accept a love I actually deserve, and am always caught up in dumb ass situations with people who don't deserve to even talk to me. He literally know all of this. He knows me better than anyone. He knows everything bad I have ever done, and he still loves me anyways. I am seriously crying right now because I have wasted so much time and hurt him so many times, just because I don't love myself enough to actually accept someone who actually treats me nicely. I am crying because he asks me more questions about baby than my baby's daddy does. He asks and listens to every little detail. He loves me despite how horrible I have been to him and despite the fact I am having someone else's baby. And he LOVES my baby, and is so happy for me no matter what. Gosh I'm so stupid.
