Broke up with my Girlfriend for a dumb reason and regret it.

So i started to get back on the dating scene few months back and found a really nice girl , whom she later became my girlfriend. we had great chemistry , hung out a lot and went on few trips together but everything went downhill for me when i started having intercourse with her , the issue was there was bad odor which i though came from her vagina during intercourse , which lead me not to have sex with her and later did not feel like seeing her and pretty much ending our relationship . few weeks later i had a one night stand with another girl and during that time the same smell came back which lead me to believe that its something else that is causing that bad odor . came to realize that it was the type of condom i have been using (thin latex) and it was my first time using that type of condoms since i had no idea condoms can give that type of smell. I felt really bad and stupid at the same time for reacting the way i did.
