I want to start by saying I'm looking for anyone to condone my actions. I know I'm in the wrong and that I've been selfish. I'm not sure what I'm looking for here, but I think I just need to vent somewhere where no-one knows me, so apologies for some vagueness (and for the length of this post).
I'm almost 40, married over a decade, together for almost two. I work full-time, Husband can't work due to severe mental health issues. We have no intimacy - not much physical touch at all - and no sex for a few years (practical, emotional and hygiene issues). He doesn't really go anywhere or do anything, just distracts himself gaming all day. Doesn't really do anything at home - we live in a tip but that's partly my lazy fault too. He doesn't look after himself or seem to want to improve his or our life. He is pretty much always angry, lethargic, depressed and irritated. We do have our in-jokes and things we both find funny, and I know he loves me. He knows me better than anyone and puts up with my own struggles.
I have buried my head in the sand for a long time, but it's dawned on me recently that we don't have much of a life. We're pretty stagnant; just flatmates that share a bed and a bank account. All the responsibility and life admin is on me and I keep making really bad, lazy money decisions. We're in a lot of debt and I can't keep up. The future feels pretty bleak for a number of reasons. I'm not happy or content or fulfilled (which I do acknowledge is all my own responsibility). I hate admitting this but I resent his illness and his lack of enthusiasm for life. I feel dragged down by it; it affects everything. I know that's not fair - none of this is his fault. He is funny and kind with a wonderful heart, strong morals and good intentions. And I do love him dearly, despite what I've said and what I'm about to say.
Recently I did something that I can't take back, and I don't know if I can live with it. Telling him could push him over the edge, when he already hates himself and feels life is pointless. He struggles to hold onto life daily. But I feel like every day is a lie now and he doesn't deserve that.
I've always fancied other people, which I know is just human nature. The levels of crushes and fantasies are up and down, and there's not really been anyone for a while. But a few weeks back I had a moment with my latest 'crush', who I work with and have not known very long. I was drawn to him quite quickly, I liked being around him, and actively put myself in a situation where it was just us, after we'd both had a few drinks (but tbh weren't massively drunk). He kissed me. I genuinely wasn't expecting it, no-one else has come onto me for almost two decades, but I didn't push him away. I kissed him back. And I didn't stop him as he took my clothes off. Some things did happen, we definitely crossed a line, but we didn't have sex. I stopped that. I admitted I wanted to but said I couldn't - I think the shock and guilt properly kicked in. I will say at this point - he knew I had a Husband, and I knew he had a Wife. He said what happened was spur of the moment and he's never done that before - I don't know whether to believe him as he's very charismatic and persuasive and seemed pretty unfazed by what we'd done.
Weirdly, and this will make me sound like even more awful but after the initial shock wore off, I didn't actually feel much guilt. I just wanted to do it again, and this time go further. I know that's wrong. He's all I can really think about and he knows that. I do have proper feelings for him, but most I think are based purely on lust - as cringy and cliche as it sounds he has awoken something in me; a desire to enjoy life, to find passion and joy. And for a bunch of reasons, I don't know that I can do either of those with my Husband.
I always thought I had morals and integrity; I never thought I'd ever cheat on him. It also never crossed my mind that one of my 'crushes' would want to have anything to do with me. My self-esteem is basically zero so I never really thought about it. But now I'm contemplating my entire future and it feels so selfish. It's not just about this new guy either - I'm 90% sure it just happened because we get on well, there's a bit of flirty chemistry, and I just happened to be there when he was horny. But it's got me thinking about what else could be out there - even if that is just adventure and some fun. It's not necessarily a 'grass is greener' situation, and I may end up alone. But I already feel pretty lonely with someone who doesn't really want to be here anymore. Someone who I have now betrayed, and who definitely deserves better than this.
TL;DR I'm selfish and unfulfilled and I crossed a line with someone who is not my Husband. Not wanting to live a lie or break his heart but now contemplating my entire future. Depression sucks the joy out of life and I've made it worse.
