I know it’s stupid of me to be pining after the person that I broke up with. I was going through a very rough episode, he was visiting family and had been gone, and I broke up with him over the phone. We hadn’t seen each other in nearly a week, even though we had basically been living together for 11 months. He started dating a new girl two weeks after the breakup. It’s been almost four months, and they’re still together. We haven’t spoken the entire time. He seems not his normal self, from what I can tell. He hasn’t posted any photos of her on his Instagram, even though he used to post photos of me all the time (I feel it’s significant). My best friend and another close friend think that he misses me, and that we have a chance of getting back together. I had a dream that we got back together this morning, not like a normal dream but a super realistic snapshot of a scene that I sometimes get that can take hours or years to actually happen, but it happens. I hate that I can’t stop thinking about him? I’ve been talking to other boys and been getting asked on dates, but I haven’t gone in any yet because the more I try to get close to someone else, the more I miss my ex. It really feels like we shouldn’t have broken up... There’s no one else that I think I would be as compatible with, and I know it was my fault for not keeping myself in check in the fall. I just don’t know what to do or who to talk to. I want to try talking to him, but I’ve heard from his friends that he feels bitter about me (at least like two months ago anyway). 
It’s starting to warm up outside, soon plants will start growing and the sunsets will be so pretty, and I’ll want to share the experiences with someone who doesn’t want anything to do with me.
I’m really going off what my best friend has said, that he probably misses me, and that we have a chance together.... It all feels like it shouldn’t have happened. We had plans for where we were going to move, and had been arranging an apartment together, and really had intended on spending our lives with each other. Now he doesn’t post photos of his new girlfriend, he isn’t excited about introducing her to his friends and people that he knows the way he was about me... He’s living with her and her parents, in their house. He doesn’t have a car at this point and relies on her for rides. He’s lost two jobs in the four months since I broke up with him.
I don’t know what I’m looking for with responses, other than opinions and thoughts and maybe relatable feelings and experiences...
