Of course. Your partners should always be aware, no matter how scared or ashamed you are. Im not saying its going to be easy because its not! Its going to be hard, i had to do the same thing. I was so afraid that my boyfriend was going to just get up and walk away but he didnt. It just showed me that he really loved me and i didnt feel so alone anymore. If you care about that person, you should tell them because, just like you and I, everyone has a plan. We dont want to mess anything up for anyone or be blamed for anything, you know? Try not to worry so much. There are many people with this situation and we are still trying to find help on it.
