One night me and my boyfriend where tell secret as a trust thing. So it waz his turn and he joked about aids, he found it funny but i didn't and its affecting my mental stability. Should i leave him or not.

Damn... I would definitely not have sex with him anymore until we both get an aids test together . That is nothing to joke around with I would just keep it real with him and tell him you scared the out of me and if you want to continue on with the realtinship you must get tested for aids

You should let him know how you feel and also suggest an AIDS test to help you to get rid of your doubts. You said you were joking around. Why would he joke about something so serious? You should have caught him on it right away.

Err on the side of caution, don't have sex with him, and if you have already, get tested. I assume he is an ex now right!
