It has to be more than her being "nice" and a strong Christian woman in herself for you to be suited to each other. John Wesley married a woman who seemed nice and was strongly supportive of Methodism, and therefore a strong Christian woman in his view. But he never stopped to consider whether he really loved her or not. So he got married and it turned out as a disaster. She became of dominating woman, and when a young Methodist preacher went visiting he found her grabbing Wesley's hair, screaming at him and pulling him around the kitchen table. The reason why he spent 25,000 hours on the back of his horse, going around all the Methodist gatherings in his ministry was that he didn't want to go home, and preferred the company of his horse than of his wife. So, be warned. Just because the woman is nice and a strong Christian does not mean that she is suitable for you. I married a strong, nice Christian woman, but I found out that she saw me as the best of a bad bunch in the church and didn't want to be left on the shelf. Although I loved her, she didn't love me in the same way, and after eight years she walked away, not wanting to be married to me any longer. Seven years after that, I met my second wife, who did not seem to be as strong a Christian as my first wife, but she had a great character and she loved me and I loved her. We have now been married for 28 years and are best friends. I am 70 years of age now and she is 69, and quite honestly, I don't know what I would do if I lost her. We have been through worse trials and challenges than anything in my first marriage, but we went through them together and our mutual bond carried us through, and so in spite of those things, we have had 28 years of happiness, and still are happy with each other; and we have a wonderful, 26 year old daughter whom we are very proud of.
So, don't marry the woman if you don't love her. You will regret it, believe me. What is a red light in my system is that you describe her as a "strong Christian". She might think she is stronger than you and might dominate you instead of walking beside you. Also, another red light is the influence your family is having on you. You don't marry a woman because your mother thinks she is suitable for you. Once you are married, your mother will still be an influence and will try and control your marriage for you. The Scripture says that a man and woman will leave their parents and cleave to each other. Problems and heartache come when parents try to control and dominate a marriage. Believe me. This is what happened in my first marriage. Her family, not Christians, convinced my wife that I was a religious nut and a no hoper who will never amount to anything. That is what damaged our marriage.
While married to my second wife (in the seven years between marriages I gained a teaching degree and a university degree, which would never have happened while being married to my first wife), and after being married, I went on to complete an MA, and in the last five years, a MDiv degree. I have also written several Christian books. My second wife freely supported me in all of these mastorates, my church work (although she is not fully involved herself) and our home is a pleasant, peaceful, welcoming place to anyone who visits us.
So, I hope this helps and clarifies things for you,
