Relationships are definatley not easy! Unfortunatley it is a part of life with the one you love, to take the good and the bad. The only advice that I could give right now would be to talk it out with him, just make a date and stick to it. Tell him exactly how you are feeling and try to get to the bottom of why is confused. But do not force the issue as this might have the opposite affect and might push you guys further away from each other! All women everywhere in the world will be behind you 100%
