I stayed loyal all throughout my first major relationship. It ended after the girl cheated on me for a co-worker. After the heartbreak, I treated myself to a few no-strings attached sex.
Nung napagod na ako with having all that fun, I started to pick myself up and focus on building my career. Not yet in the peak of my success, pero malayo na ang narating. Nasa point na for that cheating ex to realize what she missed out on (in her own words when she approached me to ask for closure). And I am good with that.
