is he too young for MLC?

[WAS32]

So I haven't been able to post for a few days because my whole world changed in an instant.I went to the concert and had a great time. H had way better seats and was trying to rub it in my face at times, but I had way more fun. He looked so sad that night. And very lost. After concert we were texting a little. He wanted to know where I was so he could go there too. I said no because he was with OW and I wasn't going to have good night ruined with drama. So he kept telling me where he was and wanted me to come see him. I told him no and that I was headed back home. It's an hour drive from where we were. i sent him a text saying good night when I got home and crawled into bed. A couple of hours later i woke up to him kissing my neck telling me how much he loves me and can't live without me. I was shocked and starting to get a headache. So we crawled into bed and went to sleep. The next day we talked for quite awhile and had a really nice day together.

Anyways, to make a really long story a little shorter he has been here until today. But he will be back tomorrow with his belongings. He wants to come home and has been helping me with moving furniture around and putting all the camping and x-mas stuff away. (something I usually have to do by myself)

I was felling a little smothered today though. Not sure if that is normal. I am a little scared about him coming home. And how much should I know about what has been going on in the last 5 months? Do I ask about OW? I think she is out of pic, but I still don't know if anything really happened there anyways. How do I rebuild my trust for him again?

I know I have a million questions about this, guess just a little nervous right now. I know I have to put my heart back out there if I want it to work this time, just a little scared.

Thanks for reading, just tring to figure this out!
