I've been with my partner for 5 years. Last year, he dumped me because we were living together and couldn't stop arguing, and he didn't want to take it further. The whole breakup was super messy and I actually found out I was pregnant a week after, to which I had a termination. I was a few days later and he was not the best through it, telling me if I had any doubt then that was non consensual because I always said I'd get an abortion before. He was moving away for work (army) and I had planned my whole life to move with him too, which ended up he went and I stayed in our hometown. So I was dealing with the breakup, termination and him moving without me.
Anyway, I finally got over it months later after thinking I was literally dying with the breakup. I enjoyed being single. I loved the attention. I was 22, so I was finally able to experience "fun". I loved feeling desired and like I was actually a catch. I was out constantly with friends and just was so excited to wake up every single day. During this time, I kept in touch with DP and we weirdly came to a neutrality where we didn't argue but couldn't let go. I never actually got with anyone during this time, or even dated. Just enjoyed attention.
Anyway, 6 months pass and DP asks to start seeing me again, and it's like a brand new relationship. We don't argue, it's as if it's entirely someone new. I feel different too, I don't start arguments like I did before, and I'm not anxious anymore. I feel like my self esteem and worth is back. However, during this time I was single, I used to speak to someone online in a sexual manner. It was purely fun and he used to love to buy me things, that was his "thing" and I loved being showered in gifts.
During the first month of our relationship, said man got in touch and we exchanged a few sexual messages. It was 5 messages in total. Since that night, I have felt sick. This was 8+ months ago. I told him straight after I could no longer talk and I was taken. I deleted the app I used to speak with him on and never went on it again. But I deal with guilt and shame every single day, to the point I am completely obsessing over it. I feel so evil and awful, just like an inherently bad person. I don't know if I would have felt this bad during what happened previously, but I feel bad now because things are so different. I don't know what came over me, I should never have done it, but I beat myself up daily and I just feel so sick to my stomach. I have cried and cried and been on edge day after day, I've not had a break for the last 8 months from this shame.
