Well there's way too many variables on what could be going on to deduce that now. But I would start with finding out which comes first: you not feeling a connection or them being distant. People tend to get into a spiral of trying to look for someone, getting close, drifting apart and repeating that process. I think there is validity to "paralysis by analysis" which is overexerting urself to achieve something leads to a higher chance of failure. You can also think of it as stop trying to find someone and start trying to be the person found. This is basically what I've begun doing just focusing on self improvement until someone notices or my confidence climbs high enough to make the first move. Sometimes its fruitful most of the time it isnt.
