h is in mlc, now threatening divorce...

[Gnosis]

I'm glad that you have maintained your 3 things per day. Keep them going. When you find the first two become a habit (within 2 weeks of consistency) keep them going and find new substitutes.

h has been a real !@#$%^&...staying away and doing my own thing!

Good.

he still has a way to push my buttons and upset me...

If you think about it carefully you will realize:
1) Your buttons are being pushed because you have expectations and he is not satisfying them
2) You allow him to influence you. Find a way to neutralize the effect he has on you because only you can control the way you react.

he cant stand to: be in the house with me, in the car, do anything...turns into an arguement...

I know. It's tough. The only option left for you is to walk away. You need communicate what you feel is unacceptable behavior and communicate it to him. i.e. Set some rules (boundaries) and enforce them.

what the heck do i do but walk away? could bop him a good one...

LOL. Oh, I know how tempting that second part is...

he starts all this and then is more aggrivated when i walk out??

Too bad. He needs to learn how to treat you respectfully. Anything less and you're a doormat. Communicate your boundaries.

isnt that what he has done all along?

Yes.

he doesnt even make sense and the arguments are over stuff like what kind of boots the girls are wearing???

He's looking for reasons to justify his actions. DON'T GIVE THEM TO HIM. Avoid these senseless attempts. Laugh them off.
