<human>: Can you succinctly summarize the text in 1-3 sentences?

The guy [25M]  I dated for almost three months is dumping me [25F] by just not responding to my texts. It's blowing my mind.  While I will admit that I didn't feel like I knew him very well after spending kind of a lot of time together, it's still pretty shocking to have someone that treated me kindly and respectfully to do a complete 180 and cease all conversation as a way to end things. 

My question for fellow redditors is how should I proceed? I tried calling/texting.  Not excessively, just inquiring how we was. I really don't want to come off as desperate but having a conversation about this is something that I feel I need and deserve. He's a really awful, guarded communicator which I suspect plays a large role in this.  Is there any way to get through to someone like that?
<bot>: The guy I've been dating for nearly three months is ending it by ignoring me.  I'd really like to talk to him so that I can feel some closure.
