I think I’ve made a huge mistake

I think everything was a mistake so ima take you back to two three months ago...

I met this guy on pof we talked for a while and finally met up now I was home drinking with my friend and he came over and we had sex he’s 49 I’m 28

After we had sex we continued to talk but everytime we meet up we only had sex so we got into a relationship but we argued because I feel like it’s only sex cause we don’t go out his excuse is (I sent to much money trying to get my car out and fixed and bills etc)

He came and spent three days with me he didn’t have money the first day because the money never came through on cash app so I paid for breakfast and put gas in his car now I feel like because I asked I should pay so I did but not once has he taken me out he always says it but don’t so I cooked for him etc it was good him spending time with me but idk I woke up this morning and now I’m just over it and we also said we wanted a baby but only if it happen and we don’t use protection I did get tested and my test came back negative so I’m good but now I’m thinking if I am pregnant what ima do I know I’m making stupid decisions but it’s also my life but 🤦🏽‍♀️💆🏽‍♀️😒

Update so I haven’t been updating on here and we did have sex on my ovulation date but I hope I’m not pregnant and I don’t believe in abortion oh and I have no kids

UPDATE

SO YESTERDAY I WAS OVER IT SO I WASNT REALLY TALKING AND HE TEXTED ME my vibe is off and he’s taking a step back I was okay with it so we break up and he basically threatened me etc but If I am pregnant I’m just getting an abortion I want nothing to do with him
