So about 7 and half years ago I was 2 weeks into my relationship with him and he went on a work course. And he messaged a girl from the hotel he was staying at she worked there. I found out as I saw her name on his Snapchat ovbs was abit like wtf is this etc he said she’d gave him her Snapchat and they just spoke about general stuff etc, right I know it’s bizarre to keep worrying over something that happens so long ago but I cannot keep thinking well what if they slept together? What if something happened and I don’t know? I did message the girl too and she said he didn’t say anything to make her think he didn’t have a girlfriend. I’m just worried before we was official he slept with someone else but he was so honest about that and at this time he did tell me he didn’t know if he wanted a relationship no excuse to do what he did I’m not saying that. But I’m just worried. I know it was so long ago do I need to just forget ?
