am I wrong?

so a little back story I don't believe in true love or love at first sight I do believe you can love someone after awhile say 3 to 6 months I also don't believe in marriage I feel like it's a cage and a way for someone to control you. anyways my bf is mad I never want to get married even though from the start I said I didn't want to now he's pushing me to even though my other reason is he cheated until 6 months or so into our relationship with his ex. I also found out he was with me to make his ex jealous. so my question is am I wrong for never wanting to get married or fully loving him?
