Hi, welcome
Couples differ as to their boundaries. Some dont discuss boundaries until their unspoken boundary is breached which is the reverse of what it should be.
Eg My wife and I knew each other 25 years before we married 13 years ago. So we knew each other as best mates. She knew and I confirmed when we dated that emotionally I'm closer to females than males. I am more at ease but that doesnt mean I'd form an emotional attachment beyond what is appropriate and we went into detail what was inappropriate. Then there would be no misunderstanding.
With young couples these boundaries can be breached as part of getting to know each other or issues like what you experienced., troubles at home, short fuses and so on. If you can recover from these straying tendencies that arent affairs then there is for some couples an acceptance in the long run of mistakes and temptations that you both can recover from. The decision to move forward is one that only each individual can make.
So its your call, will you allow his temptation on this occasion to happen be forgiven with the reassurance it wont happen again? Can he understand and accept that the stresses in your life were such that the relationship suffered to a point whereby he was unhappy and took that course?
These two crucial question can be best answered at a counsellor and you'd be amazed how effective it can be. Also a GP visit to assess your mental health with anxiety and other issues would be beneficial. Often we go to the GP when its too late.
I think you both have a good chance of recovery from this period and you might need to reassess your arguments and how to recover from them quickly. Here below is a post I wrote a long time ago dealing with how to deal with arguments and it really does work if you both stick to the process.
