My girlfriend and I have been together for a year-and-a-half, and it always seems as if she is playing games with me. When I talk about the future, she says she doesn’t know if we have a future together. When she sees how upset I get, she teases me and says she is joking. I don’t know if she is joking because she never wants to have those conversations and it is getting to a point where I don’t feel any stability when it comes to my personal life. I want to be with someone who wants to build a future together, and I don’t get that vibe from her. I want to end this relationship but if I even mention it, she will become possessive and clingy, and I will be confused all over again. What should I do?
You should go with your instinct and not by her behaviour. If you don’t feel stable or find that this relationship is as meaningful to her as you would like it to be, you are only delaying the inevitable. Her changing for a while to avoid breaking up isn’t leading to any meaningful change in your relationship, so you have to look at the big picture instead of how she is with you this week or this month. Tell her why this isn’t working out and, if that doesn’t have 
any impact over a period of time, give yourself an ultimatum and do what is best for you. The sooner you put this behind you, the faster you can move on and, hopefully, be with someone as committed to a future together.

How do I get over a crush on someone I have had for years? He is with someone now, but I can’t go on dates with anyone because they never measure up to him.
No one may ever measure up to that person but, the facts state that he isn’t with you, which presumably means he isn’t interested. What choice do you have?
