To be fair, cause you know I love ya, I think maybe you should find another way to find ME time. Or do it in a way that does NOT threaten H. Like take your mom, or insist on him coming (find a sitter).
You're still in a fragile state, both of you, with trust. I know that you are trustworthy, and he should just believe that, but would it hurt to not push that envelope just yet? To maybe extend a few gestures to let him know that you want him to feel safe? It's a big deal him opening up and telling you that he feels threatened. Basically he feels that he screwed up and you found a person that made you happy, in his eyes, perhaps BETTER. That would make me feel insecure too.
I know you think backing down from this is him controlling you with his insecurities, but this time, I think it's not control, but you doing the nice thing at this stage in your M. Prove to him that nothing is there, it shows that you love him and care for his feelings.
Maybe, he will do the same for you. I think he's still insecure with your love, so it may be a way to show him that you DO love him, listen to him when he opens up.
