Hi Mako,

Sounds normal. Your natural love languages aren't a perfect match, which requires effort on her part to remind you what she needs, and effort on your part to remember what she needs.

This sounds more like "acting how she wanted" for awhile than an improved mako per se.

Stonewalling. This kills relationships.

Oh no! This is an easy 180, one I'm surprised you didn't learn your first time here--stop fighting. You 100% control whether you get into fights. It sounds like you were headed here even before the fight, though.

I think you missed a boundary here that would have been helpful, here. Walking away from you shouldn't have meant she also got to walk away carefree from her responsibilities to the children.

This sounds like your biggest goof so far--tolerating a situation you disliked, building up resentment towards her, and then fighting. Both partners are usually responsible for a failing relationship.

Unless it ends in make-up sex, do fights ever go well?!

Well done!

Yay!

I get it. Your wife's commitment was low enough she wasn't willing to put in the effort but was willing to try as long as you did, and then you stopped trying when it didn't move quickly enough. Maybe it would have worked out if she were more receptive or you tried longer, maybe it would have ended this way either way.

There are obvious positives to this!

Sounds.. reasonable? It's been 3 years since she first asked? I wouldn't be surprised if between the workaholic hours and the hours in her bedroom on her phone she's started or about to start an EA.

It sounds like you handled the conversation well.

This seems patently untrue. Learning from one failed relationship isn't a panacea. I will be a better partner in my next relationship. You and I will never be perfect partners!

Mako, I'm sorry you're here. I don't see anything in the above painting your wife as evil or you as a fool. I hope you continue to write about your journey here. You already know the relevant links.
