I've made a stupid mistake. A few weeks ago I bumped into an old fwb. We spoke on fb remembering the good times and he asked to meet up. I told him I was in a relationship but ide be happy to meet to talk. I'll admit we were flirting through the messages and had arranged to meet up. I'm 99% sure I wouldnt of slept with him, but now hes blocked me. I've already left the house so now I'm just sitting in asda car park waiting for enough time so I can go home because I told dp I was going to see a friend. He didnt ask any details and I didnt provide any but he is a good man and I am so ashamed of what I have done.
I feel so stupid. Do I just go home admit all to dp and hope he forgives me? Or do I just slink back in an hour pretend everything fine and put it behind me. I have never thought about cheating on dp before and I'm sure I wouldnt but it feels wrong.
What should I do?
