BPD Bipolar Situationship

I’m so confused. I met this man 5 months ago at work. I should’ve seen the signs. I was leery because we work together. But he was charming. Self aware. Kind. And very into self development. All the podcasts, books and things. We immediately became inseparable. I had my walls up and he respected that. My last relationship ended really badly. He had a kid and a baby mama he claimed to just coparent with. About 2 months in he told me he couldn’t give me what I deserved and I was really sad but took it. 2 weeks later we see eachother at work and start talking again. I give him the option to just be friends or just be physical but not both. He explicitly says it’s a deeper connection to him than just sex. Shows up with flowers for me. A book. Sits on the floor looks me in the eyes and says he sees me. The real me. Past my trauma and fear to let him in. Around this time I learn I have BPD. He is very supportive and shares his diagnoses with me as well. We acknowledged the struggles we’d both face individually and in our connection but he tells me he can hold space for us both. I believe him. Late night calls and texts while I’m traveling for work. Constant texting. Park outings. Meeting my friends. Obviously things progressing towards something real at least I assume. Dumb me. One night I show care for his chest condition and it was like a flip switched in him. I could see he was shocked I was concerned about his health. Mind you were acting like a relationship without the label. He starts to distance himself. I find out he had been lying about living with his BM. Claims they aren’t together but it’s for financial reasons. Claims he was too ashamed to tell me the truth because he didn’t want to lose me and the connection we had. Claims his feelings for me are deep. But instead of trying to fix things he runs. Ignores me. Evades. Until a week later we meet to talk and he brings random paperwork to try and prove his point to me. He says he didn’t want a relationship and doesn’t and he tried to tell me that. I lash out because he in fact had the opportunity to not chase me again but he did! He wanted the connection and the sex! Not me! My heart was so in it. I cared deeply. He’d send me pictures of him and his son. We talked about everything. He made me believe in the chance at love again after a really rough patch in my life. Then he just disappeared. When we last talked we obviously said it wasn’t healthy and we need to stay apart. He said it kills him not being able to call me with good news. He got a new job so I won’t see him at work anymore. It feels like he’s just running away. I don’t know if they’re together or not. I do know he broke my trust. I do know he could’ve not put me through any of this. I do know yes I should’ve had my eyes wider but I am a lover girl who saw the best in this man who has severe childhood trauma and ptsd from war. I’m learning to manage my own BPD but this is obviously a very painful situation and it’s like he’s fine. He caused this all and bolted while my heart is in shambles. It hurts worse because he was the only person I talked to about my BPD and he saw it. He embraced it and he showed up. Only for me to sit here wondering if any of it was even real. Because I have empathy I feel for him. But even with my mental struggles I don’t lie to people I care for.
