Friends (venting)

. • ..
Alright so I'm 17, this is my senior year of high school.. I started high school with loads of friends.. But now that it is senior year, I literally only talk to 1 person (my friend from 6th grade).. Well I've been dating this guy since December 2 years ago in 2013 (we are still together, a year n almost 7 months).. My friend (from 8th grade) were talking n she said how nobody asks about how I'm doing or where I am.. That's bc I'm always with my boyfriend.. But the thing is all my friends stopped talking to me bc I've been dating my boyfriend.. He's a good guy.. He has done nothing wrong.. I literally don't understand.. I feel like j don't have anyone to talk to anymore except my mom , brother n boyfriend.. Literally they are the only people I have in life.. Is this normal? Idc if I have friends or not, but still it would be nice for people to know I still exsist lol .. I just want someone u can have a normal convo with or vent to n they listen ( except my bf lol ) .. N my friend (from 8th grade) will send me pictures of my ex n how he is doing.. When I don't care.. Its just annoying lol ..
