Heartbroken💔😩

Im hoping someone can relate to this. I had been with my boyfriend almost a year, until 5 days ago, when he broke my heart and told me he didn't love me anymore. Previously, in our relationship, about 4 months ago, he told me he was losing feelings for me, but begged me back the day after and bought me all sorts to make up for it. Well as you may imagine, things were hard for me, I found it difficult to trust him and ever since that moment, he went through hot and cold stages, one minute telling me how much he loves me, wanting to be with me all the time and then the next, he would ditch me for his mates, and act so funny with me. Sometimes when we argued he would get a bit aggressive and push me, tell me to fuck off, but I was still so attached to him and he was my everything. Well the Monday before the break up, he ditched plans with me to see his friends instead, turns out his "friends" were actually, a mate of his and two girls, one of which he'd previously slept with. I was so upset, said we needed space and didn't speak to him for a few days. He started acting strangely, doing things he wouldn't usually do, so I asked to meet him, hoping we could sort things out and get back on track. But as soon as I met him he told me he couldn't be bothered anymore and told me he didn't love me, so I left. I cried for two days and didn't eat for 3, I've been so devastated, but a few days later he changed his picture on Facebook to a photo of him and his mates and his arm around the other girl he met on the Monday (the one he hasnt slept with). It shattered me completely, he doesn't care about me and I still love him so much, he was my bestest friend in the whole world but he let me go so easily, I'm so upset and just need people to speak to about it, if you've ever been through the same thing, comment please, just need someone to let me know it'll all be okay in the end, because right now, I feel lost without him, he's all I want and all I've ever wanted, and to think he doesn't want me is the hardest thing to deal with.
