6:
Heres a little more about my take on things.
Had I not posted yesterday, this thread may have dropped off.
I like that you keep coming back. You ARE trying to learn more about yourself. No matter what, hanging around this site and reading will bring perspectives and thoughts that you may not have considered.
Your dating a younger woman.
She has been referred to as a F-buddy. Lets END THAT. She is single, so is he. Doesn't matter who may have FIRST referenced it that way, it is disrespectful terminology for both parties involved. Please refer to her as LF, as in Lawyer Friend, or some other term that is comfortable to 6.
Instead of a whole bunch of wining ang dining, you went to SF at her apartment soon after the D was final and xWW flew out of your life. 6 certainly hasn't been "playing the field" and "hooking up" with all the other eligible ladies at the gym.
If this is the type of relationship he is comfortable with, then he is allowed that.
I believe Marsh is asking 6 to look closer into WHY he can have these somewhat uninvolved emotionally relationships like this. It seems to be something that is part of 6. (I will NOT make any jokes about him being a lawyer, and what would you expect? LOL,

;))
Along this same line, I asked 6 to look into his "picker" to find out why he makes these choices in women. There is something missing, what that is I don't know. But for 6 to HAVE a long-term successful relationship, he better find out why. THAT is what Marriage Builders is all about.
I don't think that 6 is looking only at the financial angles that some have posted about. If your money is more important that your relationship, than you are missing the point of MB.
If you disapprove of him having SF outside of marriage, then that is an opinion. (Yes, I certainly abused that one....I have learned much here) He is with a consenting adult. She doesn't work for him, she is not dependent on him, and she is making these choices with her body as well.
L can be secure with 6 because it works for her, and for HIM right now. This relationship continues, in a number of years, thier relationship might move to a deeper, more complete level. And it allows L to say to the persistent ones, "I'm in a relationship, now"
I DO think that 6 has excellent an relationships with his children. He just has troubles with adult women. (Guys, don't ALL of us?) Continue to learn here, 6. You will gain some better insight into this. I did.
You gave and gave and gave to your prior WW. She had an A, and your M never recovered from that. Lets try and construct a new model for your next long-term relationship. That's the MB goal.
