My man might have given me an STD and is now distant because I brought it up again

(TL/DR at the end)

I’ve been with this person for 3.5 years. We were a very on and off couple for a long time. We finally came to the conclusion that we should not be exclusive with each other. He goes to school 4 hours away and we tried doing exclusive long distance and it wasn’t working. As well as other reason but they’re not that important to this particular situation. I told him that it’s fine so long as he wears condoms with those he sleeps with (among other rules as I wasn’t really 100% on board). Anyway, he comes back home from spring break and his college. Everything is perfect, I stay at his place and all that. He tells me he has a doctors appointment and that he thinks he has a UTI but he’s not sure. He’s bouncing ideas off me cause I a med student. I asked him if he was using condoms with other people and he told me yes. So I make a doctors appointment for him the following day and think nothing if he. He wakes up and leaves me sleeping to go to the appointment. When he gets back he tells me that they don’t know what it is but that it might be an STD. I told him to tell me all the truth and if he was actually wearing condoms with these people he is hooking up with. He said yes, but that one broke one time. That he pulled out and but another one on and didn’t think too much of it. Well I start flipping out and he is understanding. He lets me yell, screaming, cry, the whole nine yards. I told him I don’t want him sleeping around anymore and he agrees that we’re solely together now. He won’t find the results until Monday or Tuesday. We leave the “fight” ( I don’t know if I can even call it that) and we continue our day. It was then time for me to leave and I told him I would see him on Monday or Tuesday depending on when he wanted to hangout. He said that it depends on the test results because he is scared if it’s positive I might hurt him. Now I’m a tiny girl (5’3 133 lbs) and he’s a pretty big dude (6’3 250 lbs of muscle). Worse I could do is punch him and honestly it would literally hurt me more than it would hurt him. I know he said it half joke if half not. I then start to panic again because no one wants and STD and my parents already don’t like him for us being on and off. My parents would find out cause I’m on their insurance if I have to get treatment. I’m telling him all this and he just gets mad saying “just say you got it from someone else” and just being annoyed with me. He walks me to my car 3 feet in front of me when he usually holds my hand. I ask what’s wrong he said he was just annoyed. I asked him why to which he responded “oh I wonder why”. Before opening my door and closing it when I got in. He waited until I rolled down the window to kiss me goodbye. He then said to drive safe while walking away and into his house. Normally he was kiss me a few times and wait till I was down the street before i left. I then sent him a snap because of streak (I know it’s dumb but it’s our thing) was dying. He didn’t open it at all. He was online until 3 in the morning and still didn’t open my snap. I went to work the next day (today) and still nothing. I finally got off of work and found he replied with just a picture of his feet. On his story he had posted how he got hurt. I immediately called him to make sure he was okay (and to make sure he was okay with me without directly stating it). He answered and at first it was monotoned. I then proceeded to ask if he was okay, what happened, if he needed anything in our voice that we talk to each other (just loving voice nothing crazy) and saying my live and baby. He then lightened up and called me baby in our normal voice to each other. Well when he was done explaining he was rushing off the phone. I said I loved him and he didn’t say it back. I then took a nap and snapped that I had a dream about him. He usually asked what that dream was but he sent me a pic of his feet with “lol”. I noticed he was at his friends house who got their wisdom teeth taken out so I asked how they were doing. He then replied with a kissing face with “later will do”.I believe it was but it not sure cause I was distracted by his haircut. I bring it up to my friend and he was like “he’s distancing himself from you and that he might leave you but if he does he’s an asshole but it’s a possibility” I start balling my eyes out and call a mutual friend of ours that I know what say anything to him. Our mutual friend said that my man loves me a lot, that we’ve been through so much together that he won’t leave over me this. That he’s just freaking out and that guys are like this and super sensitive more than girls. He just doesn’t know what to say and that he’s processing it and to give him space I just don’t know what to believe. Because my man isn’t being reassuring at all, and we had fights and out of no where he breaks up with me. I don’t know what to do. If I should wait till he contacts me or contact him and when to do it. Whether or not bring up if we’re okay (he kinda gets annoyed when I do that because I’m a paranoid person/have anxiety). I’m scared he’s waiting for the results and whatever they say will determine if he stays with me or breaks up with me. What should I do?

TL/DR: My man might have given me an STD and got mad that I brought it up a second time after he told me the day he got his test done. I’m scared he might leave me depending on what the results are because he’s being distant. Should I give him space till he contacts me or should I contact him and when should I do it?
