lost

I'm head over heals with my on and off boyfriend lets call him T, who happened too be eachothers first. We have a connection that no ones really understands, but we had a past that if you were there too see it was pretty rough. We dated for 2 years straight head over heals in love, he cheated and it's been complicating ever since he's a different man. After gradutaing we ended up talking again but this time i seen a change i saw the guy i fell in love with all over agin, and i opened my heart too him once more. It was going perfect and i mean perfect for 7 months til my birthday came and found out he was sexting. I'm heart broken and can't move on, is it wrong too love someone soo much and have him say the same thing? What should i do? I am so lost in what i want, and no one seems too undertsand were i am coming from.
