What is happening?

At first he was damn sirious. he like me from back 2 years. even he proposed me not for love actually for marriage. after sometimes he want it slow. slowly It becomes like situationship. but last time I talk he told me that one time he did casual sex. and I said I got hurt for this. after 2 days I saw he remove all the models and girls fr instagram. I don't know it was for me or not. Last 2 days we didn't talk. I am a little bit confused about things between us
