It is not unrealistic to look for someone who will tell the truth. I am honest as is my husband and I would not date someone I thought or found was not. I don't know what sort of information the guy you are dating is omitting or what "truth" he is skirting; relationships are all different like the people in them and sometimes there are what I would consider good reasons for omitting and skirting. I would discuss with your boyfriend why he omits or skirts as well as the type of stuff he omits or skirts. If it is about drugs, then he is probably not interested in not using them so you should put that in your equation of whether you are interested in staying with him but, if it is about who he talks to and you have jealousy issues, that could be different. I would try to identify the actual problem; lying/omitting/skirting is a defense, not usually a problem in itself.
