Wow, that was from someone who has filed for D? Heck, it sounds like a Hallmark greeting card for happy anniversary. Believe me when I tell you, do not trust anything he agrees to until it's in writing and done. I made the mistake of giving in after W made promises and she just "forgot" what she had promised or "changed (her) mind" and, of course, she "can't help that she changed (her) mind" (yes, that was what she said. Like her mind is some separate thing that she has no control over!).
From what he wrote it sounds to me like he should be taking you on a trip around the world, not dumping his M! Use this as proof that he is just not in his right mind and remember that as your D progresses. Don't give an inch! Oh, by the way, in TX unless the S CAN'T make a living because of disability or illness or such, there is no S support. Doesn't matter if they have a job yet or not. If they are able to work, no support!
