I disagree because I understand the you already HAVE learned how to "be Ian and be by yourself and learn how to live life without a significant other in the picture".
That's what this ordeal makes you do, even if you do it kicking and screaming the whole way. You have done it.
I understand that conflicts that are arising for you with "dating" - the seeming lack of stability from one week to the next...I think this is a feeling you're going to have to work out for yourself though. And I know you will.
So 25 eh?
Not bad.
Not bad at all, old man.
I disagree also that this young woman will end up hurt.
As long as you are honest and proceed slowly and with caution, I see no reason anyone here should be objecting to you having a piece of eye candy.
Or anything else you might want.
JK.
But seriously, I see nothing wrong with it so long as you remain a nice guy.
