Heartbroken (sorry in advance for the rant)

Basically, me and my ex broke up a few months ago after he cheated on me. He implied that it was my fault he cheated because I made him feel suffocated and that he wasn’t ready for a relationship, even though he initiated it all, and making it official straight away was all his idea??

Anyway, he was the kindest and sweetest boy I’d ever met in the early stages of our relationship, I felt so lucky because I’d been hurt before and he seemed perfect. He’d brag about me to his friends, message me constantly saying how much he loved me, introduced me to his mom and dad almost straight away, I finally felt happy in a relationship.

We did occasionally argue but who doesn’t? Nothing serious, just small disagreements. He even rang me when he was out with his friends saying “even though we argue, I love you so much”

Then out of the blue, one night he just switched. He was literally like a different person. We spent almost every day together, and then suddenly he left me and that was it. Since we broke up I’ve seen him once, spoke to him on the phone twice, and we’ve texted a couple of times. I want to hate him, he wasn’t even nice to me when we spoke since then but I just miss him and love him so much. The thought of him being with someone else just kills me inside, imagining her sleeping in the bed I’d slept in, where he told me that he loved me for the first time just breaks my heart.

Anyway sorry for the rant, just needed to vent and I don’t really have anyone to talk to.

Does it get better? How do you get over heartbreak, because it’s making me feel depressed constantly 💔
