B, I know you've expressed this kind of thinking before.
You've been married twice. Been cheated on and left twice, right?
So, here are the possibilities:
1) There is something flawed about you that attracts or elicits this behavior from women. Therefore, unless you get to the root of the issue you will be doomed to repeat it again.
2) You were at fault in one, but just had a flawed partner in the other. Maybe you were at fault in marriage 1, but fixed that and just married poorly (or she changed drastically as she approached 40). Therefore this isn't a pattern, and you would be basing your "I am flawed" belief on a fallacy and missing out on a great future relationship at some point in the future.
3) You were innocent in both and both times just married women that secretly were lying cheaters that were going to break your heart no matter what you did. Again, if this is the case then you would be basing not trying again on a fallacy.
Now whether it is 1-3, it is always in your power to choose to never try again. However, if it is 2 or 3, and you only being 34 I think that would be a shame. There are many ladies out there that aren't liars and cheaters. Yes 80% of all Ds are started by women. However, maybe half of those involve them just flaking out and leaving a healthy relationship. The other half are because their husband is a cheater. Or a liar. Or an abuser. So you'd be basing the other part of your assumption on 50% of 80% of 50% of all marriages. If you do that math then you are basing your assumption on 20% of all marriages (I believe that is right, since 50% of 80% would be 40%, and 40% of 50% would be 20%).
So the numbers don't seem as dubious once you start peeling back the onion. Even if I was off by 10% of the 80% it still is only 24% of all marriages! That leaves the odds, especially in your case, of finding happiness, assuming it isn't #1 above, in a future marriage much higher than you think.
Sorry, I am a math major. LOL So I didn't want you to think that 80% was really 80%.
