Big mistake

So I'm in my mid 20s & this guy, who is aged mid 40s, was good friends with my mum. She has told me he has tried it on with her & very flirty & touchy feely. A few weeks ago mum told him I was going through a bit of a bad time so he started visiting me for coffee & company. As time went on I noticed he became quite touchly feely with me, first it was hugs, then back rubs. I'm naturally shy & was a bit weary of this but he assured me he was just being 'friendly' & being naive, I let him. He told me he enjoyed my company, that I was beautiful & bought me gifts. One night, he was giving me a massage & quickly moved in to kiss me. I pulled away at first, but then started kissing him back. One thing led to another & you can guess the rest. Soon afterwards I began to feel guilty, ashamed & messed up because of it & I told him this. He visited me a few days later for coffee. He started cuddling & kissing me, saying he was so happy at the mo & that he was off work the following Friday so he would take me for lunch. He was busy with 'work' following week & my shame & guilt was eating me up so I text him telling him how I felt, esp going behind mum's back. He was working long hours & didn't seem too bothered. He started contacting less, I was a mess & wanted to know where I stood or at least what kind of friendship this was. Mum then told me this guy had been back to hers, giving her back rubs & texting her again. I felt sick & broke down crying, telling her the truth of what happened. Obviously she wasnt happy & broke off her friendship with this guy & threatened to get him sacked from his job etc.. He called her, saying his head was messed up, it was a mistake & that he has no other friends.. But mum said he had crossed the line. I told her how sorry I was for going behind her back & how he had charmed me, making feel special whilst I was in a bad place. Suppose I just wanted someone to make me feel wanted as I felt lonely, & this guy knew this. Just can't handle the guilt & how much regret I have. Been crying for days & can't cope x

There are many different visions of this story, you've probably heard it already. Once there was a scorpion that need to cross a river, he sees a fox and the scorpion asks the fox if he can ride across the river on his back, the fox says no, you'll sting me and I'll drown. The scorpion then says I won't sting you because then we would both drown. Hearing this the fox decides to give the scorpion a ride across the river, half way across the scorpion stings the fox. The fox says why did you do that, now we will both die, the scorpion says I couldn't help it, it's in my nature. You knew what this guy was after because he was already seeing your mum. Everyone wants to feel wanted, sometimes we make mistakes and look for it in places we know we shouldn't. We all make mistakes even your mum, I'm sure that if your truly sorry she will forgive you, but it may take some time.

Hello thanks for your reply. I didn't know or believe he had tried it on with my mum until afterwards, which was just awful. And I did believe he was just being a friend at first as he always promised he would never try anything with me. Mum just found out this man is married also, which he always denied. It's all just one big horrible mess. We told the wife what he has been doing to single females in the town we live in & now just trying to forget about him x
