I drove past his house

21F So long story short I’ve been seeing this guy for about 3 weeks now we hang out everyday 25M , I spend the night every night . Everything is going good with this guy as I see it I’m starting to catch feelings for him a lot , He woke up sick this past morning and was mad because I left and had a nail appointment but I said I would be back later to be there for him … so I asked him if he wanted me to go to the store and grab him anything he insisted he wanted night quil and soup . Whatever you need right I go to target get him a nice card, soup, tea, ginger ale ,sweatpants , chocolates ,night quil. I come over and surprise him I get upstairs he says thank you immediately says can you make me soup so I storm downstairs and make him his soup brought it to him . Cleaned him house , did his dishes and took out the trash everything . I go upstairs and lay with him for a few and say hey I’m leaving I need to let my dogs out and get mad at me and says why are you leaving again. I get he wants me to stay but I have other things to do and I don’t wanna get sick so I still leave he sends me a paragraph saying how I’m a little girl that I don’t know how to take care of a man on and on . When I went and got him a care basket and he said he didn’t ask me to clean his house with just a nasty attitude. I was like I can come back over just had to take care of the dogs and he’s like no you can come back tomorrow after I go to urgent care so I’m like okay. So later that night he didn’t say anything to me he said goodnight at 8pm which is suspicious but ok . Me and my friend decided to hang out (F/21) and we got some drinks and we’re going to head to her house so she’s like let’s drive by his house so I’m like okay so we see a white care which is his ex girlfriends car and I instantly freak out so I pull up her address and when to her house just to make sure and I was right. I feel just betrayed and that was just a stab in the back because we’ve been sleeping together for 3 weeks … ik that’s crazy to drive by his house but how do I even approach this situation like what do I say to him to actually make him feel guilty because what he did was beyond wrong and I don’t deserve that when I’ve been nothing but genuine to this man
