I am in a relationship for two years now. We have our fights but mostly it’s going well. Although there is one thing that bothers me a lot. He still has contact with an ex girlfriend. Apparently she is the only one of his exes that he ever really loved, that she is beautiful and everything about her is perfect. He likes all her photos on social media and sends her messages. I mentioned to him that it makes me feel uncomfortable but he says I’m being silly and that they are just friends. Well actually more than friends he said, like family. His family also like and comment on all her photos too. I feel like they would be delighted if they got back together. It is making me feel so bad about myself. He makes me feel inadequate when he mentions her. Am I overreacting?
