So my boyfriend and I been going out for 1year and almost 11months. We have a 5month old baby. He made me delete every social network accounts that I had but he still had facebook and instagram. Dont get me wrong, we loved each other and were very happy with each other. I been with him through his hardest times. I was with him for 5months when he was sent to a youth correctional facility. I was already pregnant. I wrote a letter to him EVERY SINGLE DAY and called him all the time. he came out early and we were so happy. I gave birth in august and we were SO happy.I was with him when his stepdad passed away. I lived with him for a while too.Then lately we been getting into more fights. I found girls numbers in his phone. And seen old messages to them. And just the other day, his mom told me she found another girl in his bed. My world was crushed and I tried to kill myself. Now he's left me, and told me to get out of his life. I cant stop crying and I still love him ALOT! What do I do:'(
And also to add, we were going to get married. But now he's just changed. His mom told me that she'll help me thru this and will help me become a successful woman. And she's been crying for me too because she said I'm such a nice, beautiful, loving girl and I didnt deserve this happening to me. But lately, I been crying all day, every day. A part of me is asking "why me!? What did I do to deserve this hurt and pain??" And anoyher part of me wants to just end my life. Another part of me wants to just try to move on. But I gave my life up, I gave up everything for him, and I never imagined a future without him. So now I'm lost and confused. I can't eat anything, I can hardly sleep... How do I move on if he's all I ever wanted...
