When someone says they "love" you it may not mean to that person what it means to you. You are correct, all I know about these relationships is what you have shared of them. You don't have to accept, nor am I expecting you to accept anything I say or suggest based on what you have shared. A man can be with several women and love them all, but doesn't stay committed to one woman and may be more committed to something else, example alcohol, needing to be with more than one woman, loves something "more than" like his career, his sports, etc. etc.
