Help💔💔

Sorry this might be long.

Okay so I am one of those girls that have a hard time letting go of the past.. it eats me away sadly.

Well I my boyfriend/baby's dad has cheated on me.. a lot. Not physically, but emotionally. He'd text girls and tell them all this bullshit. Well back in 2013 when we got our first place together, he started talking to a younger girl.. and I guess she became is new soulmate .. well fast forward to Jan 2015.. I moved to another state for a couple months and came back because I missed my family. Well I gave him another shot in July.. it ended in August due to him STILL TALKING TO THE YOUNGER GIRL. Well here I am giving him another shot. He no longer has a working phone, but I can't trust him, I try but I can't. I feel stupid for even giving him another chance. I don't know what to do. He wants to get married, but I don't wanna be divorced before I am 22... Advice would be greatly appreciated... 😭😭😭😭😭😭😵😭😭😭😭😭😭😭😭😭😭😭😭💔💔💔💔💔💔💔💔💔💔💔💔💔💔💔💔💔💔💔💔💔
