Maturing

Alright guys, so I am 21 and married. I married at 18 and ever since I got married I stopped having friends due to the fact that I felt like they were very immature and I was already entering the next level of my life. Everyone at my age is usually partying and drinking, while I’m here planning my next life goals like buying a house and making sure my husband and I are financially stable. I mean I do like to have fun once in a while, but not all the time like people around my age usually do. I feel like at times it’s hard to make friends with people my age because they just aren’t at the level I am. Is this weird?
