Need advice. Long post.

Okay so my boyfriend has trust/anger issues. Now I have two male friends that I have been close with for years that he knew about way before we even got together. One happens to be an ex from high school. We just figured out we wasn’t meant for each other so just friends worked for us. I promise you guys I am not lying I have not had sex with anyone else since we been together. But getting to the point. He is really hard to get through to and we had a fight and I felt like at the time I couldn’t talk to him. I reach out to talk to my guy friend about it (high school ex) and he’s like “yea we can talk I’m in the area step outside.” So it’s hot, I’m a little sweaty, it’s about 11:00 at night. My boyfriend and I had been texting the whole time I was sitting out side talking to my friend. He asked where I was and I told him I was home. He said he felt like I was lying and cheat on him so he came to my apartments and went on the opposite side, parked the car, and walked to my apartment and was sitting on the steps texting me asking why I’m lying I told him I was home and then he stop replying so I say my goodbyes and I walk back to my building and he’s just sitting there like where you been. I told him I was sitting outside. If he wasn’t trying to be sneaky and go on the opposite side of where my building is he would have seen me sitting right out front by my car. He got mad and said I smelled like sex and went completely off. The next day he asked could he go back to my apartment while I was at the nail shop. I let him. When I got home he threw a box of condoms at me saying that im no good and stuff. He then tells me that when we first got together he found condoms hid in my closet with two in the box and now it’s one. I had no idea the condoms was there I swear I didn’t. My ex before him worked through the week and we was only together on the weekends. We always used those brand of condoms so I know it’s his and I told him that he probably hid them from me or something. I’m short and in the closet it was on the top shelf under the Teddy bear according to my current boyfriend but I didn’t use it I haven’t slept with anyone and I had no idea they was even in there and he went through my stuff while I was away. I don’t know how to feel or what to think. What can I do? He don’t believe me and I’m honestly not lying.
