I have been seeing a man for around 4 months now. We are long distance but the relationship has been good, he seems in to me, lots of contact, visits and making plans. We met online and spoke for a few weeks before meeting. The first date was one of those ones were you know you like each other right away and everything followed very naturally. I soon "ended" any other chats I had going on online, just for my own sake, as I knew I wanted to focus on this guy. We never spoke about exclusivity but I always felt that it was clear from both of our actions that we were only with each other. He has referred to me as his girlfriend on one occasion, I've met one of his friends and overall I feel pretty secure.
I've now decided to broach the subject of exclusivity, as I realise it's not a great idea to just assume these things. I am pretty confident that he will be on the same page going forward.
My only concern is this: would it be reasonable for me to ask him if he has still been talking to/seeing other people so far in the relationship?
If he has, then technically he has done nothing wrong and I recognise that. On the other hand it would be slightly concerning if he has been this loving and "boyfriend-y" with me, whilst pursuing other women/keeping his options open.
The reason that I would even suspect that, is because I recently went on to the app where we met and looked at his profile, saw that he has updated his location to the place that he moved to just a month ago. (This particular app doesn't follow your current location, you manually set your neighbourhood/hometown.)
So what do you think, should I just ask if he wants to be exclusive going forward and leave the past in the past?
Or is it reasonable to ask if he has been and is still talking to other women, has been on dates etc whilst we've been seeing each other?
