Dear Katie,
I've been with my girlfriend for three years now. But two years into the relationship I used to tell her it was over. If the truth be known, I couldn't imagine life without her and that's what's bothering me. Why do I doubt our future together?
Marc, Letterkenny, Co. Donegal

Dear Marc,
Many people act like this in a relationship; it's a control issue and a form of attention seeking. Your mind seems to think that if you tell your girlfriend you're going to leave, and she begs you to stay it's reassurance for you that she still wants you. Seek professional help or stop messing around.

Dear Katie,
I've been going out with my boyfriend for a year now and recently he saw these raunchy sex positions on TV and wants to try them out. What should I do?
Lauren, Sandyford, Dublin

Dear Lauren.
Sex is an intimate thing between two people. You should only do what you feel comfortable doing. Tell him you're worried about disappointing him, if he respects you he will understand.

Dear Katie,
I recently found out that my dad is not my real father. It turned out that my mother had an affair and got pregnant with me. My dad found out about the affair but took her back anyway. And they have been telling me this lie for 22 years! I feel so betrayed by both my mother and my father. I feel a lot of hatred towards my mother. I love my dad very much, he has been such a great father to me, but now I don't understand how he can love me like he says when I'm not really his daughter?
Sarah, Tralee, Co. Kerry

Dear Sarah,
I know this must have been a shock to you. What you thought you knew of your parents was not what it seemed. You must now look at the bigger picture. Your dad has loved you for 22 years and has never treated you in a way that would make you feel like you were not his own child. In relation to the way you are feeling about your mother, yes, what she did was wrong, but if her husband (your father) was able to forgive her then you should also. Explain to both of them how you are feeling.
