Dear Ashmita,
There is no minimum or maximum communication in any relationship,since it varies from relationship to relationship.However, your communication should be transparent and consistent.The other person should realize that what ever you are communicating,you mean it.And off course,conveying your needs in a very cordial manner would ease the situation.Frequently sending text messages or phone call don’t play a very important role.Rather making couple of calls and talking to him would strengthen the relationship.For effective communication, you need to bring that trust and transparency in your relationship and with little efforts you would be able to that.
Try this and I am sure you will be happy.
