Confused

Br
Ive been wanting a baby for little over a year my fiance wanted one first and i kind of warmed up to the idea but after a year and a half of trying i figured ill focus on school work and bettering our relationship im only 21 and sometimes i think i made the best decision when im out with my girls drinking and doing things but theres always that part of me that comes home and see my future brother in laws on fb with their families and half my friends have babies i cant help thinking must be nice 😩 i get a little jealous idk what to do to stop myself
