I’ve been with my OH for just over one year. We live together, but he works away during the week. I’ve just found out that he has been cheating on me with his ex. Seeing me on weekends, and her during the week. This has been going on since the start of our relationship, up until a couple of months ago. He’s been telling us both that he loves us and we’re the only one for him. The other one is “Just a friend” or “No way, I’d never go back to her”. It came to a head recently, when his ex and I happened to run into each other. I asked him about what I’d discovered, but he got very defensive and threatened to end our relationship, claiming to be sick of my “Paranoia”. I have evidence that it has been happening, so I know it’s not paranoia or my imagination. He’s admitted to having changed since the start of our relationship, even though he hasn’t been specific about how he’s changed, and now says that he wants to build a life with me / buy a house with me. His ex has suggested that he’s only with me for my money - not that I have much! Do I put the past down to experience and carry on as if the relationship started recently (Since he last slept with his ex), or do you think I’m letting myself be abused and exposing myself to a life of him lying and cheating?
