Newbie: Is this MLC and how do I GAL?

[Some Day]

I posted yesterday, but not showing up. So here goes again... H texted me yesterday inviting me to an event at his work this weekend. This is strange to me because his affair was/is with a co-worker and it is widely known at work. Why would he invite me? Anyway, I said yes. One of the things he complained about our marriage was that I did not support him in his career and woulnd't attend work functions with him. So, this is a 180 for me, I guess.

Later that day, he showed up at the house to tell me some "news." He had good news about passing a certification test he had taken to advance in his career. I was very happy for him and told him so. He said he wanted to give me the news in person. He left to go to the gym.

In the evening, I went to the gym (not expecting to see him since it had been a couple of hours). Well, as soon as I got there he came over to me. It seemed like he had been waiting for me to show up. He spent an hour with me teaching me some exercises and how to work some of the machines. When he left he gave me a tight hug and a peck on the lips.

Here's the irony, today? No contact from his whatsoever. I honestly don't know what to think. I know he still has contact with OW and his other female friends. Why would he reach out to me? Is he testing the waters with me?

Thoughts?
