Cheating

I know this tale has been told a thousand times but….

So I have been dating my boyfriend for a little over a year. We just moved to an entire new state together, got a dog, an apartment, etc. Everything was perfect.

Until I found messages on his snap chat that he thought were gone from March. He had cheated on me at a bachelor party. And was trying to see the girl the following day. All while telling me he loved me and couldn’t wait to come home to me.

I know people have been in tougher situations with children, split finances, marriages etc but I just don’t know what to do.

Once a cheater always a cheater?
