My [22 F] boyfriend [24 M] asked me to take a pregnancy test, and I caught him drinking the pee?

Hi reddit.

So, let me preface this by saying that my boyfriend and I have a very healthy relationship and I love him a lot. We've been together coming up on three years (next month!) and moved in together in January right before the whole pandemic thing, so far it's been great. For the record, my boyfriend has never once even alluded to being into watersports in any way at all. We are both, I thought, staunchly anti-kink.

From the beginning, he has always been very paranoid about getting me pregnant. We both agreed early on that we never want kids, so we take extra precautions. I am on the pill, and he wears condoms just to be safe. I personally think we would be fine just using birth control, but two of my friends have gotten pregnant on the pill so he insists on doubling down, which, fine by me, better safe than sorry I guess.

So, everything has been going fine... until about 2 weeks ago when we were having sex and the condom broke. I tried to calm him down, telling him it was no big deal because the birth control and spermicidal lubricant on the condoms meant there was an astronomically low chance of me getting pregnant, but my boyfriend freaked out. Told me we absolutely had to take a pregnancy test just to be safe. Still, nothing too strange, so I go along with it and we buy one of those packs of three from CVS, I wait until 6 days before my period, piss on the thing, and tell him I'm not pregnant.

That's when it started getting weird. Even though the test read negative, he insisted on me "finishing off the pack" and peeing on the others "just to be sure". I read online that you're supposed to use your pee from first thing in the morning because it can get diluted throughout the day and become more inaccurate, so I tell him I'll wait and do another tomorrow and then the next day.

Well, the next day I go to pee on the ol' stick and I notice the one I threw away is no longer in the trash can. I decided it wasn't too strange as it could've been buried in tissues or something. So I finish up my business, leave the stick on the counter for him to see himself, tell him I- miraculously- am still not pregnant, and that I'm going to take the trash out.

That's when I noticed that the pregnancy test really was nowhere to be seen in the trash bag. I shook it all around, looked at it from different angles- nope, no test.

Aaand then I go back into the bathroom to wash my hands, and I see my boyfriend holding the test, uncapped, with the porous part in his mouth, making sucking sounds. He immediately looks embarrassed, and pulls the stick out of his mouth so fast it makes an audible 'POP' sound. He started walking towards me while apologizing, but I completely freaked out and walked out of our apartment to get some air. All of my friends have been saying I need to leave him for violating my privacy. I haven't spoken to him since this happened (two days ago). Honestly, I don't even know how to approach this situation. Help me reddit. Can this be saved?

TL;DR: Boyfriend was very insistent on having me take a pregnancy test, and then sucked the pee out of both tests. We are otherwise very compatible and have been together so long I don't know what to do.
