Getting married will not solve your problem because you two still have nothing to talk about after the marriage. You should try to find some common interests with your bf and spend more time doing things together.
If he is not willing to change, you have to. Learn what he likes and discuss what he likes. If he likes NBA, learn to watch NBA so you can watch with him;
but word of advice first, if you try to force yourself to something you do not like, you will feel pressure and someday it will come back to bite you. |
