If you were involved in a volunteer position you would pick something you were passionate about. You would love it so much that you would give your time for free.
With a romantic relationship, you should be involved because you love it. Love is unconditional, otherwise it is conditional-love and that always comes at a high price – your life. Love is something which should be given for free or it isn’t love at all.
If love had a price, pick a love that is priceless, be involved for free and want nothing back in return. That way you will never be involved romantically with someone wishing you were somewhere else or with someone else.
WARNING choose a love with someone who feels the same way about you.
