Do I have a right to feel the way I do?

So this guy I been with for a year and 7 months has been getting fights with me and told me he hates me and wants nothing to do with me. That I’m nothing like him and his type. Then he tells me he loves me and he can’t picture a life without me. That I’m the best thing that has ever happened to him. I don’t know what to believe anymore. I just feel so heartbroken and hurt. I been crying everyday and throwing up but he said he wants to work things out. I love him but I’m hurt.

Also he wanted one of his female friends back that I don’t trust bc I heard a rumor that they slept together in the past but he said I need to be more trusting and accepting of her. So I let him have her back. So I don't know anymore.

Him and I would text everyday for a year and 8 months and made memories of going to the lake and going out to eat and other things and he said that meant nothing to him then he says the memories we share are important
