Thank you so much for appreciating my efforts.
Freedom is one of the prime virtues of love. Unfortunately, you do not have it and you still feel that your husband loves you a lot! I do not know what your ideas about love are but for me it definitely includes freedom of expression, understanding, consideration, sacrifice and lot more. Try to put forward your feelings about the whole issue without blaming or accusing any one. Make him aware about your attachment to your parents (that any child would have for his/her parents). Any loving husband will understand this provided it is properly conveyed in non aggressive way. At the same time you should also convey that as grand parents they have equal rights and desires to spend some time with grand children, in an assertive but non aggressive way. Rather than trying to patch up between them, try shift your focus on your duties towards your parents. You owe some duties towards your parents and you are going to fulfil that without bringing other issues in the way, you should make this thing very clear to him in very polite but firm way.
