| I am happy to hear anecdotes as well as evidence based stuff. There are stories where people say love fades, sex fades, but the relationship still goes strong for a long long time. But, the thing is what make you fall in love with someone? To choose them as your life partner? What kind of assurance does one need to be totally free and secure mentally and physically in front of (with) one another? |
Loving and liking someone are very different sides of the same coin in a relationship.
It is most important that you like your partner as they are and they do like you as you are. Everything else can be negotiated from that base.
But if you fall in love with someone and then think 'they are perfect except ... but I will change that.' you set yourself up for unhappiness from the get go. Same for your partner and worst if both have this idea.
Trust & respect seem to be functions of this little detail from my experience.
If you trust your partner to like you how you are you won't find a need to hide things from them, do things different or lie about things. Trust is easy with this base.
Critique born from disagreement about how you are or behave doesn't exist too then, so the accumulation of small bickerings and injuries over time, one of the biggest killers of relationships in the long term, does not happen (someone below linked the famous 'scar tissue' gist which is spot on here).
I am in a long term, open (but not polyamorous) relationship.
The open part helps tremendously with the sex not fading. Sex with your partner is just much better after you had sex with someone else. This is an experience I had in all my open relationships (not all my relationships were open though). And it is seconded by the conversations with my resp. partners and friends in similar constellations.
I won't go as far and say open is better for the long term, but if you have the kind of trust I mentioned above anyway, it is 'free' (no/little negotiation required) and it sure helps.
