Have I made the right decision?

My fiancé and I have broken up. We have numerous issues and finally it all came to ahead
I snooped into his messages and found that he had been
dirty texting a girl. I confronted him about it and he
said it was stupid and didn't mean anything he said
he did it because I belittle him and make him feel stupid
I had no idea I was doing this and he has never told me
I make him feel this way. I suggests counselling which he
rejected.
This is a long line of issues our sex life is struggling
and while I was looking through his phone I saw
a suspicious message with just a hotel address.

While I know sneaking around is wrong, is breaking
It off the best thing to do? I'm devastated
And heart broken needing some advice.

Yes, breaking up with him was the right thing to do.

Yes you cannot trust him and all his excuses are bull. Be grateful this happened sooner rather than later. It would be much worse if you were married with 2 or 3 kids. Now you have the chance to meet someone more loyal, honest and faithful. You deserve better than this.

Forget counselling and move on with your life. Hes not worth it. He has shown you what he is capable of and marrying him would be absolute hell for you the next time and the next time and the next time he does this. It will take time to heal emotionally but you will get through this and you will meet someone else eventually.

Cut all contact with him and let him go and f**k himself. The prick does not deserve you

If you are finding it difficult to cope-get some individual counselling. You need to be strong now and put yourself first. Hes a lying cheating ass and the only way hell truly learn his lesson is if he loses everything right now. Otherwise he will do this again.

I am supporting your decision. Take strong decisions in significant moments.....

Hotel address? He's either banging random chicks or...hookers.
