Hello Friend, Good that you are seeking a help here. Any relationship will be successful and long-Lasting if there is trust, open communication and give & take between partners. If any of these goes for a toss, it takes time and sincere efforts to recover.
I would suggest both of you to go for a counseling especially pre marriage assessments type to better understand each other and identify the gaps to work from both of you.
