Sarah, stop analyzing the past. The signs were his actions—or lack of them. 
Love isn’t a feeling; it’s consistent effort. If you weren’t a priority, that’s your answer. I learned the hard way that inconsistency is a dealbreaker. Protect your energy like a warrior. 
Don’t let anyone make you question your worth. For the future, your non-negotiables are your shield. If his actions don’t match his words, walk away. Set boundaries now and demand the respect you deserve! Stay strong.
