Should i even try with my boyfriend anymore?.?

So, we havent been together very long... been together 3 months. . It will hurt me to leave him because we got so close... i even was so positive about him i let him meet my two children recently. So, awhile back i told him he can look at porn.. just not to do it around me.. and dont tell me about it.. well he told me about it today.. and even told me what damn porn star it was.. im like.. sickened.. and grossed out... my stomach is all sinked feeling.. cant believe how big of a pig men are. Its so disgusting.. and last week he brought some damn porn for us to watch.. it was some 50 cent groupies video. I was like..... what the eff.. are we serious right now...i tried so hard NOT TO GET MAD.... and he wants me to talk about it with him because its better to talk about it... and i cant.. because then it takes me back to my past relationship with my kids father.. and his porn addiction.. and it was so gross to me!.. ITS JUST SO RIDICULOUS TO ME! i just wanna scream at him the way i would at my ex.. and im just so over this now.. i feel like i cant stand this crap... it makes me more and more insecure. I just cant do it i dont think. ... and when i get to feeling like this i wanna get every cosmetic surgery possiable... ..... just wanna cry..... please dont answer with mean comments. I will report you. Thank you.
