I disagree. Giving to get is not my idea of love, it's not how I love nor how my boyfriend(s) have loved/love me.
For example, giving my boyfriend a BJ. I don't give him a BJ because I want him to go down on me, I give him a blow job because it gives ME pleasure, I enjoy giving him pleasure in that way, it makes me feel good, it turns me on!
Course it turns HIM on too, so it's a win win, and he will give back to me, perhaps not at that moment in the same way, but he will reward me for it - give to me, reciprocate.
And vice versa. A balance of give and take at different times in different ways.
I also disagree that love is conditional.
Love, even romantic love, when it's genuine and pure, is unconditional, otherwise it's not love, it's selfish and self-serving and to me that's not what love is.
What IS conditional is remaining in the relationship. If my boyfriend were disrespecting me or abusing me, treating me poorly for example, I would leave the relationship but I would still love him. At least for a time until I healed.
The love doesn't just die because your partner isn't meeting your conditions, whatever they may be.
Your desire to stay in the relationship dies, but not the love.
Not in my opinion or experience and I have experienced it.
I left the relationship but it took nearly two years to heal and to stop loving him.
