Don’t make decisions based on guilt or what you think you should do, for it is only in being true to yourself that you can be true to others.
If there is something happening in your relationship that you do not like speak with your partner about it now. The longer you wait the harder it will be to deal with. If you wait and bring it up when you are angry or unsettled it will be looked at as if you are only speaking about it because you are angry. When you first notice an issue that is unsettling that is when you address it.
