My girlfriend is getting too attached

Hello everyone i am 28 with my girlfriend 27 for 6 months now life is good we see each other almost 4 days a week and i am very happy with the relationship i couldn’t ve found better partner. I am not against attachement, i am getting attached too but when we are not with each other she depresses too much and when i talk to her about it she says i am like that i cant do anything about it. And i really want to help her for the balance of the relationship
