We all have been in committed relationships where even after spending a considerable amount of time,
Mutual respect, loyalty all these are in place and yet, We kinda loose the feeling of love the adventure rush we used to feel in the beginning,
This could be because we might have more responsibilities than we had before or we have been doing the same mundane things for long, obviously there is a fix, and that we can spice up our life again by many ways and can do this forever trust me.
However, amidst all that amongst our interactions we met this guy/ girl who is a completely different personality, has humour/charisma etc and you kinda like talking to him/her.
This is an attraction!
And no no there is nothing wrong with attraction, it can happen to any of us, at any age.
However, if you feel that you are feeling attracted to someone new and your feeling love is kinda fuzzy, and if you don't tell this to your partner about what's happening, this will ruin your relationship
You should! Period.
It's a slippery slope, I have seen many falling into it but, you don't want to ruin something you built by investing your time, energy and efforts for such a long period.
Go communicate, work as a team.
