Haha, that’s odd but I’m okay with it. I’m not an easily offended person and I’ve always thought of my features as “quirky,” his seem to be in the same boat, so it’s not a struggle to see why. Plus, I guess we both smoke constantly, drink too much tea and have shite luck, so…
In all seriousness, though, I think you already know the answer to that question.
It would be one thing if you guys had an open relationship, had discussed any sex outside of your marriage, or basically had made any plans at all for this sort of thing, but I’m willing to bet that since you refer to it as straight-up cheating, you’re not feeling okay about this and you don’t have to. I don’t really have a lenient side when it comes to people violating others’ trust, as in this situation, so if you’re looking for any reconciliation tips, you might have to seek those out elsewhere.
On the upside, you’re young, you’re catching this problem early instead of years down the road, and you’re likely only just getting started at being relatively independent in the world. If you decide to cut him loose and start fresh, you’ll barely notice this unfortunate hiccup in a few years. Things don’t always work out, especially not with chronic assholes. Doing what’s right for you will make you feel all the more self-assured and confident in the future.
