I think this applies to both women and men : Don't be sleeping with somebody who had slept with a lot of people! Chances are, the relationship wouldn't last.
People with a lot of vices, specifically if they drink liquor a lot. Just like si Kuya, above me, โฌ๏ธhe specifies that if the person makes so many excuses just for the bottle - RUN.
Lastly, I like to remind everybody is that there are people who are mentally unstable. We cannot change people as much as we invested our feelings and money towards them. If somebody makes you feel bad about yourself.
Leave the relationship.
