Is experiencing or having a better love life achievable through learning certain skill sets?
I am not asking about shrewd methods to lure someone into loving or wanting you. I am asking about lifelong habits that can make people fall in love with you that eventually remains stable and long lasting.
Rule applies here, work on yourself so that you're a better person to be with in a relationship. Work on physical health, good diet, mental wellbeing, work through any past traumas or bad experiences (perhaps with a mental health professional) so you're not carring baggage to future relationships, work on impulse control, emotional control and pretty much the most important one above all others, communication skills.
These things basically apply to all relationships, romantic, professional, friendships, family, etc and are generally good things to work on for your own happiness and wellbeing too.
