Archie,

Usually when we invest a lot of effort into something (specifically people in this case) we do begin to grow sort of feeling for that person, whether its love, attraction, anger, etc. You don’t have to feel guilty for trying and letting things go if they don’t feel particularly right. Try to take 10 minutes to clear your mind, remove all of the ideas that are floating around in your head (maybe I should work harder at it, am I being shallow, what if I lose something great) and in silence ask yourself “is this right for me?”. Your answer may come, and by the way you described the relationship it sounds like you’ve genuinely put in the effort and opened your heart and you’re feeling a bit of resistance which is ok. You’ve done what you thought was right so far and you’ve handled the situation very well. Give yourself some credit!
