I feel kinda bad now....

So me and my ex broke up a few months ago but we still lived together slept in the same bed done all that except we never claimed each other after we agreed to not be together welllllll I moved out about 2 weeks ago and went back to talking to the guy I talked to before I got with my ex and we’ll me and new guy have been messing around and he told me he wasn’t nutting in me (allergic to condoms) and I trusted him and well today my ex asked me to come over and talk and I was like okay maybe it is time to talk and so obviously I showered and put on matching undies and bra Bc I always know where our talks go and we’ll it went how I thought it would we agreed to continue to see each other but not exclusively well while I was there I got a call from the new guy I ignored it and told my ex about him and everything Bc the new guy is my ex’s “friend” well they aren’t friends they just play Xbox together and he took it fine and well the new guy left a voicemail apologizing and he wouldn’t ever say what he was sorry about so I called him when I got to my place and he said I’m sorry I really am and if anything comes of it I’ll take care of it I swear and me I’m hella confused and I was like slow down I’m not getting what you’re saying and the man goes I wasn’t honest with you and boyyyyyy I got scared so I asked him again what he was talking about and he goes I nutted in you Bc I don’t want you going back to him (the ex) as they both know about each other I’m very open with them both no need in lying to one of them and causing drama so I’m kinda sitting in my bathroom not knowing what to do Bc he swore up and down he nutted on the bed and not in me and when me and my ex slept together he always nuts in me and I’m just worried about getting pregnant by the wrong one and then having to figure out which one is the daddy and after the conversation with my ex today I wasn’t going back to the new guys house anymore and I was going to let him know but now I’m just concerned we’ll anyway if anyone had an advice it would be appropriated and if anyone has something negative to say we’ll idk why to tell you

Update: all three of us have done a std test a few days ago we are all clean I’m very cautious about that

Update2: I’m not birth control Bc me and my we’re trying for a baby even after we broke up he still wanted to try for one So I never got out on it but we had been trying for about a year and nothing ever happened I might just Bc scared right now idk

Update3: @Brie yea my ex is definitely the love of my life and I let everyone know this and even guy #2 knows how I feel about my ex like I’d go back to him whenever he calls I’d do anything for him no matter if I have it or not and he does the same for me and I’m very cautious of things when it comes to sleeping with either of them they are very honest with me as I am with them I don’t feel the need in lying and causing issues in friendships and possible relationships I think I’m worried that guy #2 would hope it’s his and if it is I feel like he would expect me to get with him but I don’t view him in that aspect at all and my and my ex spoke on it and he said he’d be there for me if anyone else ever got me pregnant he’d be upset but he’d support me but guy #2 said if I’m pregnant and it’s his he wouldn’t allow me to be around my ex or for the said child to be around him which I feel is messed up but idk I don’t have any kids

Update4: @Natiya honey we are mature all above 24 none of us have kids we communicate with each other everything lmao sooo get the negativity outta here booboo and @C it was a day ago
