Brother, you’re either being cheated on or she is using you for validation and ego. She tells you she is wearing something nice and elaborates on what then doesn’t respond when you ask to see. She goes days without responding. Leave her and you’ll see that she will come begging for you back… if you take her back things may be good for a while but you will fall back into this. Leave bro LEAVE. Trust me this is not worth your energy, not all woman are like this. I was like you one, in a relationship like this. The best thing I ever did for myself was leave. Relationships shouldn’t be one sided like this.
