I need some advice, should I approach a woman about her husband??

So I’m staying in a hotel right now indefinitely.. the hotel is awesome and has a huge community table so I meet new people almost everyday and even made some good friends from up north.. I’m in Florida..

the other day I met a couple guys; father/son.. both nurses..

I’m engaged so I am not looking for anything, I’m just a social butterfly.. (fiancé works a ton so is normally asleep by 9) so I’m hanging out with these guys and a whole other group..

this one guy immediately singles me out because we are both Hispanic so we are talking about the differences of living in Florida and where it feels like home and what not.. from the get go he tells me he is married and she is almost 6 months pregnant.. I’m like “how wonderful, good for you, congratulations” well a few hours go by and I invited everyone to walk down to the beach to catch up with a couple other people who went down to drum circle.. of course, he is the only one who wants to go.. on the walk he says “no disrespect but you’re very pretty” and I’m like “no, yeah, thanks! But your wife is way prettier” (oh, I forgot, earlier I asked to follow him on Instagram so I can see the baby and his wife) he kind of ignored it.. at that point I made every conversation about his wife, the future baby.. like I flipped almost everything he said.. well now he is messaging me in Instagram like everyday!!! And being very suggestive!! I literally bring up his wife constantly and he still is all like “we should go dancing” “ I wish I gave you a piggyback ride” like WHATTTTT???

Well I found her in Instagram and I feel like I should tell her but at the same time she is pregnant and I don’t want to stress her out..

I did already block him but before that he said he was coming for a visit at the hotel this weekend. I asked if his wife would be here because I want to meet her and he didn’t respond.. so more than likely he will be around here this weekend..

also, my fiancé knows about this whole thing and thinks I should stay out of it..

Update: alright, I have wanted to tell her.. because I would want to know.. at the same time I don’t know this man.. he knows exactly where to find me.. he said he was coming this way this weekend.. I think I will wait until I’m out of here.. because again, I don’t know this man..

Another update; he is my fiancé, and he knows who I am.. we have complete trust in one another.. why would I stay cooped up in a hotel when I can leave for a minute?? Every night after my kids go to bed, I wander 10 feet to the common area to get some socialization and maybe even the beach.. he knows this and he knows about this whole situation.. it’s called trust
