stop romanticizing unhealthy relationships. 
stop thinking you can change someone. you can’t. they need to change for themselves. 
stop romanticizing the idea of you two being together some day. if it isn’t happening now, let it go.
no more pouring your heart out for someone who gives you little to no reciprocation.
find someone who values your long letters and passionate attempts. this person will reciprocate, with twice as much fire.
