Mom wants me to find a guy irl..

So ive been texting this amazing guy for almost 5 months and we really want to meet and maybe start a relationship, however mom keeps dropping comments like "you always talk to virtual guys, i want you to find a guy irl" and its really annoying me because i think i'm in love with this guy and i have no idea how to make her stop and just accept that this is the way id like to meet a guy, even my granny started being annoying about it and telling me that i have to find him in university etc.... my mom knows that i'm texting him but she doesnt know how serious it is... i dont know what to do :/ its really depressing me... i'm 18 btw so technically i can do my own decisions but its still affecting me pretty badly :(
