Is it normal to have a friend that never calls you unless they want to invite you to a bday party or house warming party etc... ?

Her and I use to be very close but with age and years we grew apart and there were some hard feelings but in time we were able to say hi. She only text me to invite me to an event she's having but she never calls to talk, text me to say hi and we haven't seen each other for months.

I start to think that is she only inviting me for a bday gift or a house warming gift or something. How sincere of the friendship if we dont even talk or go out for coffee.

My bf said its normal and some friends are just like that.
