No. I think you are at an age where you are more aware Andrew logical and so the day dreaming and butterflies aren’t as intense and love has a totally different meaning.. as it should.
Most people who marry them divorce, when they look for a new partner they’re a lot more logical and... they only fall in love when things align logically for them and they realise they have a good catch.
You are waiting for the intense spark that you had when younger. In reality, just like with babies, there is this initial moment of compassion maybe (and maybe not for many mums) but the bond develops with time when you end up putting effort and seeing it reap benefits and align well with what “should” happen.
Obviously though you do need to not feel repulsed by him and have some sense of attraction to him whether physically or intellectually and be able to respect his contribution to your life because intimacy and respect are important elements for that bond to grow.
You see some mothers, don’t feel a bond at all with their own children at birth and beyond. There are many factors for that, including pnd and so on. The advice is usually to fake it until they make it, and that it will eventually come naturally. That’s because your child logically has not given you a reason to not be loved.
So marry someone who is worthy of your compassion, worthy of your respect, worthy of your love... and that you are attracted to.. and then wait for the bond to build. Until then, fake it till you make it.
