I’ve gone out four times with my male neighbour. We connected instantly and had a lot of things in common. Lots of laughter and conversations. I am however, very confused by his behaviour. Is he interested or not? On date number three, he initiated a more serious conversation with regards to seeing each other. We both agreed to continue seeing each other and that we were both serious. After me returning from my trip to London, things have not gone great. We went for a late walk, but otherwise haven’t seen each other. He takes days to answer a simple message and I’m not sure what changed. When asking him he only says he’s busy with work and finishing his thesis (we’re both in grad school). I’m confused as to why he would initiate a more serious tone to our relationship while at the same time pulling back. Thoughts? Thank you!
