OP, my heart goes out to you. My DH did this to me. Like you, we were very young when we got together and he’s the only man I’ve slept with. In his early 20s, while we were together but often living apart because of studying/work, he took any opportunity he was offered to sow his wild oats. He wasn’t honest with me then because I would have ended the relationship. Most hurtful of all are the few times he did it after we got married, while he was away on business. I had absolutely no idea until some months ago when he suddenly confessed – also while drunk. The difference is that we are nearly 50, married 20+ years with teenage DCs.
I started a thread about it on here (under another name). We’d had other problems too and pretty much everyone said I should get rid of DH. (I’m not going to tell you what to do. It’s a horrible decision to have to make through no fault of your own. All I would say is that you don’t have to decide anything right now.)
I decided to try to forgive DH and give him another chance because (1) he insists that I’m the only woman he’s ever loved, he’s never had an affair, only ONSs that “didn’t mean anything” (though personally I find this compartmentalisation almost impossible to understand), (2) he didn’t have to tell me the truth, there is no way I would ever have found out, and (3) I can’t just turn off the love I had for him. I want to grow old with him (plus I’m not likely to find any other decent man at my age – which isn’t the case for you).
I said DH could stay on condition he started seeing a therapist every week, coming home from work earlier (until lockdown started) and cutting back on alcohol. He did all of these things. We did a lot of talking, trying to understand one another. But it’s been very hard. I know exactly what you mean about being eaten up by it and feeling stuck. My head was a mess and I struggled to focus on anything else for several months. I asked endless questions about the women (which he answered patiently). I’ve asked him hundreds of times whether he’s told me the whole truth now, trying to accept that I will never know. After years of trusting him 100%, I suddenly became ultra-suspicious and needed him to stay in touch far more than he used to (pre-lockdown).
"I feel like I can’t do anything or even be mad because it was so long ago"
Of course you can. Your feelings are totally natural. You are NOT being over-sensitive! Your past life together and your idea of him have been turned upside down. You need to express your hurt and anger to your DP and he needs to listen and understand the effect of his actions on you. Telling him how you feel doesn’t have to be confrontational. But also, for your own sake, try not to obsess over the details (believe me, I know how difficult this is).
Be kind to yourself. Be proud of your integrity and the person you are. You weren’t stupid to trust him – you were just assuming, quite rightly, that he held the same standards that you live by. Enjoy your beautiful new baby (congratulations by the way!) and your 6-year-old. Talk to a friend you trust IRL. Think about what you want and need. You don’t have to make any decisions now. Sending you lots of love x
