I don’t know how to feel tonight

So idk what to consider him right now. We had sex three nights ago and Saturday I hit peak fertility and today was ovulation day. I’m not sure if I’ll get pregnant or not. Even if I do I’ll keep it. So this person I thought cared about me and sent me a message to tell me that they went and picked someone up from a restaurant and then said “just so you know” like he was doing this to hurt me. I never in a million years thought he would do something so horrible to hurt me. I have people who tell me I deserve better but at this point idk anymore. I’m pretty burnt out after 3 1/2 years. Please help me out.
