I have a jealous fiance 😟😡

My fiance been married before his ex wife did him wrong now I feel like every little thing I do or say he gets in his feelings feel like im paying for what she did to him/ he treating me like how he post to had treated her. I'm a sweet girl I been throw a lot I lost my mommy and step father I really don't talk to my real father like that and so much more but I manage to change for me and him so that we have a better relationship I did my part I don't go clubbing any more I barely drink I stay home and to myself and I go to church now. It hurts me to my heart that he thinks I'm always doing something wrong or cheating on him we been together for 6 years and been knowing each other 7 years he should be over how his ex wife did him I don't act like her I way on him hand and foot and treat him like a king its like he don't trust me the only time I messed up was in 2012 its 2017 I have changed I just don't know what else to do I'm trying my best and we getting married next year and I'm so scared. I tell him everything like he's my best friend I don't hide nothing from him at all I know how his wife did him but I could never be her, I just pray that he fine his way because I can't deal with this I can't be around my own family because he doesn't like my oldest sister but try my best to show him that I love him and that I'm not going any where it drives me crazy he always thinking negative about me, if it wasn't because of me trying to keep this relationship together we wouldn't be getting married but things change

🙏💔😞😢
