emotional abuse 💔

My man recently started a new job as a pizza delivery driver. He always tells me how he delivers to the most weirdest people or the craziest shit. Like one time he told me that he delivered to a girl and she came to the door with JUST a short robe on and bent over to get money out of her purse for him and he said he saw EVERYTHING and then proceeded to tell me how he felt about it, which I didn't like too much. Anyway, last night he said he went to a party and didn't tell me about it (I typically don't care but he usually tells me what he does bc he doesn't want me to worry). He came over today (Sunday) and I asked him about the party and he didn't say much. All he said is that it was a gathering with his friends. I asked him what friends were they and he just said "just some guys I'm friends with." I know/met a lot of his friends and I'm scared he's not telling me everything. 

I mean everything is probably ok but I'm an overthinker and an emotional abuse survivor but everything is coming back and it's stressing me out 😣

He also hasn't spoke to me all day and it's worry some to me.. I'm just afraid of him cheating or having an affair, whatever, with someone else.. 

A week ago yesterday he gave me a ring. A birthstone ring. It doesn't have any significance as in marriage so he told me to wear it on my right hand and for me to always wear it bc it'll let me know that he loves me more. I've been looking at it all day, wishing, hoping, praying that he's not a cheater and will not treat me how I've been treated before.... 

EDIT:

He told me that with his last girlfriend, he just woke up one day and decided he didn't want to be with her anymore and broke up with her.. I'm really scared that that will happen to me.. he also said that when he was with her he would fuck around with other people without her knowing and then told me to not to worry bc he would never do that to me, ever.

Idk what to do really.. I'm so confused and stressed out about this 😣
