Am I a homewrecker?

A couple months ago my husband left (due to not being ready for this much responsibility but that’s a different issue) we have a now 7 month old son together. (We’re both 19)When he left I was really upset and happened to run into a family friend at the store (you know the ones that are like a bonus uncle when you’re a little girl close friend of my parents) well later on this man messaged me (he’s married with kids and he’s around my parents age they went to School together) and asked me if I would like to go to the casino with him to take my mind off of it and I had never been. I said yes thinking it would take my mind off of things. Thinking that He used to take me to the park why would this be different. Well flash forward We’re there and he starts buying me drinks. I ended up drinking to much and the night got spotty. The last thing I remember I was in his car and he was kissing me and doing some other things. The next thing I remember I woke up in my bed at home the next day. I don’t know how far it went, I don’t know how I got home, and he hasn’t texted me or brought it up at all. I don’t know what happened. I feel embarrassed and worried about what happend. Sober me would never have kissed a married man or a man this much older than Me. I feel guilty and discusting. I don’t know how to feel or what to do. I worked things out with my husband and We’re back together but that night is still heavy on my mind latley. I can’t beleive I let that happen. I feel like a homewrecker like the worst type of person, but I also feel taken advantage of
