Search Results: should i text him

Just found out the guy I hooked up with (three times) 9 years ago is married and has actually been married for 10 years! He didn’t have social media but I came across his picture on his wife’s social media celebrating their 10th year anniversary. That means that when we hooked up he was already married for a year… I don’t have any proof or texts because I no longer have my old phone/old number. I also saw that they have 2 daughters together. On one hand I feel obligated to tell her but I also don’t want to ruin a seemingly happy family and break their daughters’ heart… Should I just leave it alone then?

(We have since gone no contact ever since the last time we hooked up, it was all very casual and I’ve forgotten about him plus I’ve been in a happy relationship ever since then. That is up until he popped up on social media and caught me off guard - my boyfriend knows about all this and told me to stay out of it).

So I don't know if it’s b/c I use the apps kind of “casually”, as in every other day/every 2 days etc. It’s kind of rare for me to message a guy daily, unless it’s at the point where we’ve met up & are msging on a different platform/texting etc. But I’m pretty big on asking questions for obv reasons; if 2 msgs have gone by and I’ve asked questions while the guy is only talking about himself/just answering me, I’ll stop replying. I’m not quick to unmatch, unless it’s known we’re not a good match after meeting or they say something gross etc. It shows a lack of interest or the guy potentially being self absorbed…am I too hasty? Is it just how a good chunk of guys are on the apps? Or should I blame myself?
