Best day for me was when I got the finalized divorce papers.
It wasn't a bad relationship, it was just all one sided. As in; she wanted to marry me from a high school age and I wasn't interested in her that way. Hung around and hung around and hung around, weaseled her way into my romantic life and while I can't exactly prove it I'm sure she did her best to sabotage any relationship I had.
I made one bad decision and eventually asked her to marry me, which she jumped on even though she KNEW I wasn't into it. I had "meal ticket" stamped on my forehead apparently. It was a complicated and confusing time in my life, and yes, in a moment of weakness I did ask her. So I can't deny my responsibility in the whole cock-up. That lasted nearly 14 years, until I met the woman I should have waited for my whole life.
But, it's kind of an odd situation. Had I not married the wrong woman first, I never would have met the woman I'm with now.
Life's funny sometimes. You never know where it's going to twist or turn.
My next "best day" will be when my daughter graduates university and I can cut wife 1 completely out of my life. Paying child support to an ex-wife for a 22 year old daughter (that the Ex has turned against you 100%) is just ridiculous, but the courts have got you in a vise and there's only one way out.....you gotta wait it out and the pay a lawyer again to terminate. What a scam....
