Is Intimate Relationship Wrong?

I had a intimate partner for 9yrs no relationship commitment thou I had multiple miscarriages surprisingly I was blessed with Rainbow baby sadly our relationship turned sour...I left him for 2yrs he came back again n i forgive him,we are intimate again and I don't know if I am Right or Wrong? Actually I love him during the 4th year but I don't think he has a idea of settling down I don't want to force him either I just know he can't move on to another girl or leave me permanently also.. he is loving recently but I don't know what he wants I am very confused if he is only attracted to me just for the intimacy or he has developed feelings for me too...Any idea how I can find out if I am wrong in being intimate with him despite all this years
