Can you forgive someone who has been unfaithful in your relationship?

The same as you! Forgiveness is a necessity but don’t hang around for more!

I have forgiven them too. I feel partially responsible for their unfaithfulness.

I am not sure about the trust part. We hand it so easily when in love. We do it sometimes out of longing and desperation for losing or having control. Like a blanket to insecurities. Once disappointed, we again place responsibility on the other person unable to see we had a choice.

Simple answer - NEVER

i hope so,there's a good chance I'm gonna do things I shouldn't. I hope I can work through things. I hope I can work through when I let someone else down and when someone lets :me down.

Depends on why where n when and wiv whome they did it wiv.

I have already.

perhaps there was mitigating ...

Depends on the circumstances, tbh; but it’s also possible to forgive someone while realizing they have no place in one’s life.
