As problems come up in a relationship, it is not at all uncommon for people to see the issues and try to steer clear of them or avoid them entirely. This doesn’t make the problem go away, since it is never addressed. This is a terrible way of dealing with problems since they just compound slowly on themselves until everything starts to fall apart.
If you find a problem in your relationship, you should make sure that it is addressed early on. The only way for the other person to know that there is a problem is for you to let them know that something isn’t going as you would like it to. This can help you deal with girlfriend or boyfriend problems before they blow up in relationship ending fights.
