I think that it's only natural to be scared of finding one's perfect partner, only to discover that the other person does not feel the same way.
The thing to remember is this; unless that other person feels the same way, s/he is not really & truly the perfect partner.
I can understand the worry about never finding Mr Right, but worrying about it does not help, and, actually, probably makes this worse.
But, after 3-4 years, I can understand you feeling a little impatient.
However, for him, it hasn't been that long, has it, because he had a girlfriend?
