Search Results: should we break up boyfriend

A few years ago, a high school friend created a dating profile for me on a website since she wanted to see me with a boyfriend (i know, weird). Anyway, I used the profile and started chatting it up with a few men, some I even know today. One guy, in particular, liked me a lot, even though I wasn't too keen on him at first. I entertained him since I was bored, but I eventually developed feelings for him. I did break it off with him because he lived 3 hours away from me, gave off very aggressive vibes, and I started to like someone closer by. Over time, he was on my mind, and we did text each other occasionally, but it was very short convos. He even wrote many poems about how heartbroken he was that I ended that online long-distance thing with him too.

Fast forward to recently, he told me he was joining the military and wanted to pursue me again. I was interested and was thinking about him frequently while he was at boot camp. Right after he came back, we texted like usual, and everything was fine until he wanted to make a last-minute trip to see me before leaving the country. I had to decline and that changed the dynamic of the relationship a little bit. A few weeks later, he informed me that he had gotten a girl pregnant. I immediately cut contact with him since he betrayed me somewhat. Now, he's texting me frequently and calling, claiming that he loves me still and cannot die without giving "us" a chance. He knew what he did was wrong and apologized for his mistakes to the point he doesn't think about anything sexual anymore as often as he once did. Do you think it is worth it to pursue a relationship with him with all of this information or should i let him be? I don't want to waste time in a toxic relationship.
