Overreacting???

I’m a little upset because I feel like my boyfriend is still in love with his ex. He calls her beautiful and model and he just never called me that or speaks to me or about me in that way. It kinda really makes me feel really bad about myself or more to I’m not good enough. Comparing myself to her. He won’t even post me on his snap for her to see we are together I feel like he is embarrassed to be with me
