Boyfriend text work colleague

[FidoO5]

My boyfriend was text a girl he worked worked with and expects me to forgive him and stay together.
We live together get on well, we rarely have same day off but had Wednesday off and he went out to play football which started at 8 but he left at 3 to hang out with the lads.
He is 27 I'm 23. I said if you don't want to spend our day off together don't bother coming back tonight and he didn't.
Next night he came home slept on sofa.
Today I asked to see his phone and saw he had sent her a message are you missing me x, because she was moved to another shop. There was also other messages between them. I'm so annoyed,

Would you stay with him or leave.

I mean - it’s ok to see friends on your day off - had you made a plan?

whete did he stay? You told him not to come back - so he didn’t.

then you went through his phone. It sounds pretty shit all round tbh.

It doesn't sound great.

What are the positives

You say she is a girl OP. Is she very young?

If he didn't bother coming home and he is sending messages like that to another girl/ woman then I would assume OP that's where he spent the night

Sorry but he might expect you to forgive him but forgiveness is only something you can decide on. And if he is not honest and open and remorseful why should you forgive him? It's up to him to earn your trust

You’re 23. Don’t spend the next 20 years of your life finding out that he will cheat on you over and over again. You’re so young! Don’t end up old and still stuck with this loser.

Go find someone new who thinks you’re the best thing to walk the earth and builds a real future with you.
