Is this MLC or WAS? Don't know what to do...

Yes, I’ve noticed that when I told him (via e-mail or text, since he didn’t call me at all) that I missed him and wished he were home for some events, he stopped texting for a few days. When there was silence on my part he would find a reason to communicate.

That's pretty typical. It's OK to reply to him if he texts, but try not to initiate them. And don't always reply right away. You want him to wonder what's going on with you, what you're doing, if you're maybe losing interest and he might be losing you.

I actually need to gain some weight . I’ve lost 15 LB in the first months after BD.

Yeah, welcome to the BD Crash Diet, it's by far the most effective weight loss tool out there

When my H told me that we both need to start our new lives, he said that I would have no problems finding somebody new, since I always get an attention everywhere I go.

He may have said that, but I suspect he'd be shocked if he thought you might actually be going through with it. My wife started dating me after my old GF and I broke up (they were friends). My old GF was PO'D! I never understood that, but my wife said "well she doesn't want you, but she doesn't want anyone else to have you either." I think this is common with WAS's, they think they don't want their LBS but if the LBS starts dating they can get really angry. I'm not saying to start dating, just commenting on how strange a dynamic it can be.

Yes, I’ve changed my clothes a little, letting my hair grow longer. I’ve been doing some things that I never did before (like going to Rodeo with the GF, taking dancing classes, etc.) I also was listening to some new music when my H was in the house.

Fantastic, keep it up!!

He is kind wondering what I’m up to. He did ask our friend at our vacation home place if we had a good time when I was there. I don’t tell him everything and he doesn’t ask.

Perfect, you want to be mysterious like this! Make him wonder!

But, I feel that this doesn’t matter to him as much as I would like to.

That's OK, you're doing it for yourself. You may have to force yourself to do these things at first, but the more you do them the more fun you'll have and the less dependent on H you'll feel. It's part of detaching and GAL.
