Breaking convenant

please pray for me so that God can forgive me, I have sin against him by promising so many things which i didn’t fullfill them.

I made a convenant with him about the man i love so much, I break that convenant for about three months,when i realized that i have i decided to change my ways and live in the covenant, after three weeks i found that God decided to take the man i love so much to another woman, I was hurted so much,i tried to commit suicide.

from that moment up to now, I’m not happy, its eight months this man still exist in my heart,I’m living in the convenant but the anger of God is still over me,i get hurt over and over again.

May God forgive me and give me last chance, I’m struggling so much.

Only God’s forgiveness can set me free!
