Prayer to change my husband

I got married this year January and living with my husband. He enjoys spending time at work if not at work he is out with friends at night drinking and partying coming home at midnight. I tried to speak to him several times but doesnt help.

He treats me like he regret marrying me and the communication lacks between us. A week ago i asked him what makes him happy and he said its night life and friends. I know i am a good wife and doesnt deserve all of this because i have not done anything wrong to him. He tells me hurtful things, i am 5 months pregnant and never got any support from him in that 5 months.

i spend my entire moments weeping to God to change him to be a considerate man who has sympathy, care and understanding that he is no more a child but a grown up man. I went to lot of priests for advise and prayer but nothing is happening and i am asking God what i did in this life to deserve such treatment. i dont have a say in his life because he always ignores me when i try to talk to him so i always keep quite now even if i see something wrong.

I LOVE HIM so much and want him to change. i feel lonely but i have a husband. i also think that he has girlfriends that they are going out with at night while i am in the house because he doesnt seem to care when i talkt to him,he is giving me signs that he is cheating as i have always found messages and got phone calls from his girlfriends, different ones. Please pray for me.

I always envy other peoples husbands that are caring and that puts their wives first. I need strong prayers for him to change please.
