Me and my ex were together for 5 years. We’ve been through so much together and it was always full of love. We know everything about each other, inside and out. He kept me sane and we were like best friends and lovers all in one. He didn’t treat me the best some of the time but I still stayed. I adored him. We broke up in October and I tried to move on but my feelings for him were far too strong. We spoke all throughout being broken up and we decided we still love each other. We then agreed on getting things sorted to get back together. He came to my house a couple of times and we had sex during those times and promised little promise about our future. I then started to get a feeling that he was talking to someone else, and he was. He’s telling me he’s moving on and that things are getting serious between them. I feel worse than the break up, my heart is shattered. I can’t eat and can’t stay asleep. I am filled with anxiety. Can anyone give me some advice?
