Hello all! This is hardly a pressing matter but something I’m just curious about what people may think about it. Over the summer I went out with a guy who I met online. We hung out a handful of times and had a blast each time. We are similar in age, each divorced, same number of kids, like the same music and sports teams, work in similar industries so it was just easy. After a few months I asked him what it was that he was looking for. He said he wasn’t looking for anything serious. So I was honest and said that while I enjoyed his company I was looking for something that had potential to become serious down the road – not a dead end highway. He said he was bummed but that he understood and we parted ways. From time to time he’d tag me in something innocuous on Instagram, comment on a story or send me a random snap. I ignored in large part with a “haha” here or a “100” there. Then two weeks ago we had a brief exchange over Instagram messenger and he texted me. After 2-3 mins of back and forth he said he was really glad we’ve remained in contact and asked if we could just be grown ups and grab a meal sometime. I said sure of course but I haven’t set anything up or reached out to him first (he’s texted every day or every other day since – and it’s been nice truthfully bc we do get on well) because it’s like why bother? He knows where I stand so.. what gives? Why do you think he’s back? I’m sure he’s just bored but thought I’d ask you all to weigh in bc I find it strange that he’d be initiating contact again with someone who he knows isn’t looking for the same thing.
