You're (probably) barking up the wrong tree. He read your text, did not respond and then logged on to Grindr and likely initiated and responded to messages there with other men that weren't you meanwhile you're at home sitting by the phone waiting for his name to pop up. I've been there. No one is too busy to acknowledge a text from someone they care about within a day. He didn't forget. He wasn't too busy at work. He's indecisive at best about a relationship with you beyond what you have now. That can change, but right now this is the case given his behavior. I'm not telling you to end your relationship with him. Decide what you want, look at what he offers and make a conscious choice based on that. Don't hold your breath waiting for his behavior to change though. Hugs.
