I'm trying so hard, what can I do?

My girlfriend keeps sending me one message text or emotionless ones. I Don't want to talk to her about it because I don't want to lose her because of my insecuritys again. But its just feels different. I mean there's days when she sends me normal ones when I do something for her like buy her an iphone, bring her lunch, and other things. Then there's days when I'm too busy at work and can't do something nice for her and she like ignores me.

She's using you. She's only interested in your money. You deserve better. She ignores you if you don't do anything of what you said and acts happy when you do. It's utterly clear that she's using you.

Leave her bro she not the one for you I just read more of your queStion
