What to do now?

Ok so a couple of weeks ago i was going through this thing with my boyfriend. I was stressing myself sooooo hard bc He was acting really weird towards me, i mean really shady. Like he always got annoyed with me and stopped txting me.Which was most likely my fault bc i thought he was cheating. But according to him he was unhappy/ fed up of me not trusting him.

So anyways just recently i just told myself "look get it together" and i just started doing my own thing like hanging with my friends and my very young aunt. Now every time he calls im out doing something and u can hear it in his voice that he's upset. Just this past weekend i gave him a really good bj( something ive never done before) and ever since then he's been super sweet lol but also super jealous and im really getting irritated. Its like if im not home waiting for his calls or if i miss his calls he'll get upset. Any advice on how to handle this bc i dont want to sneak behind his back and lie and tell him im home when im not and ive noticed ive been doing that just so he wont get upset.
