I currently have a boyfriend who I've been with for 7 months and spoke to for almost 3 years before that. Last week I stayed with my brother in his new house which he is sharing with a few others. To make this as short as possible, basically it was just me, my brother, his girlfriend and one of his new flat mates there for a few days and I think something immediately clicked between us or something. We've been messaging back and forth since yesterday and he's been kinda flirty in my opinion, so I don't know if he feels something towards me. But every time I think of my boyfriend I have always thought he's the one I'd have a future with, but it's also not fair on him to be acting like this. Any ideas on what to do?😓😓
