Thank you for sharing and being so honest. Hopefully you will find here that you aren't alone.
Sometimes things happen and we can become disillusioned.
Love has kind of done the same thing to me too and I am married. Sometimes I wonder if we expected too much at some point, like we wanted those butterflies to last and for the magical feeling you were describing to always be there. But maybe that's not really what love is...
For you, I'd say try not to feel pressure. Use this time for you to focus on you. Love you. Be your own biggest love interest <3
