I'm not sure if I'm going to be able to get a good deal on a new one.

Personally, I think your girlfriend should still be quite sincere to you, just a little bit of their own hobbies You are afraid to ignore the family after marriage, the impact on the marriage, this feeling is completely understandable, the general situation is to consider getting married to find a family man in the together with the bland life, if I were you I would also have the same encouragement. In view of your situation, it is best to talk to your girlfriend and her parents about the intention to get married (at least have a time), after all, you are almost the same age, to get married after this matter is finalized, the advantage of doing so is to tell your girlfriend from the action, you intend to get married to her, so that she will also have to take this matter to heart, since they are going to get married, it is certainly necessary to collect the heart, so dangerous hobbies, and so on. For a girl who will be married to a woman is not suitable, if this time the girlfriend is willing to give up playing motorcycle for you, then you can also rest assured.
