What should I do

[AmyMaria2]

I don't know what to do, I've been with my partner for 7 years, we have a 3 year old little boy with autism. The first 6 years of our relationship were great, I felt like we were so strong and I was so glad to start a family with him, we were currently thinking of trying for another baby.
However in April this year he left, he went back to his mums house and said he didn't want to be together anymore, I later found out this was because he felt guilty about meeting a girl on a dog walk and exchanging a few messages, I don't think anything physical happened with her, however while he was staying at his mums in may he slept with somebody else, although we were still talking and seeing a lot of eachother during this time, after 6 years and having a child together this hurt so much. I wanted him back and tried to work through things and he eventually moved back in in July.
Cut to now- Christmas Eve I go on his phone and see he's been talking to someone on an online game for months, they haven't met up she isn't local but they've spoken on the phone and messaged almost every day for 5 months, he even sent her photos of him at a concert we went to together in London, it makes me so upset that this has been going on after it took so much for me to get over everything he did back in may, I just don't want to leave him and love him so much, am I a complete mug? I don't have many friends and my son is so challenging I am so scared of being without my partner but also don't want to be treated like this, what would you do?

Im so sorry op this is awful. Especially at xmas.

You’re not a mug. Sounds like you have been very forgiving and loving. Sadly he hasn’t done the same. I think having the first situation go the fact he has again been sending inappropriate messages, now over a long period, is unforgivable.

I guess the complication is managing your child’s care. Will it be hard to manage alone? Do you have a wider support network, grandparents etc that help. Whatever happens I think you should end the relationship. You give him one chance and he messed up again. I wonder if actually he wants to leave but is too much of a coward to go through with it.

@Eekmystro thank you for your reply, merry Christmas!
I have got my mums support she is really helpful, I just don't want to ruin my sons home life an disturb what he's used to😞 I just don't have anyone else to talk to and I feel like I'd never meet anyone else now or have any more children.
I think he must want to leave me, otherwise why would he keep doing this, but every time I ask him and even give him the choice to go and stay amicable he says he loves me and doesn't want that. I just don't want to keep finding things he's done, it's so hard to get over and gets harder every time there's something new.
