Is this unforgiveable or is this me being unreasonale 10 points for you honesty? x?

I met this guy whilst i ws grieving over a family suicie..sometimes i could appear to be ok at others i felt broken inside. Anyway we had been on a few dates he said he could see us getting marrie an then one night didnt get in contact with me like he sai he would..so as i was so upset i thought i cant deal with this right now and sent him a text message saying i did not think we should see each other anymore. He did try to phone but i was such a mess i just did not answer the phone. The night before i was really upset and he asked me what was wrong but i could not tell him i was embared. Then he went on about my job that i was a "dolly bird" and picked at me the next day over breakfast i told hom not tobelittle me again and he asked for his keys back. Now i know that a bit of a long one but am i being unreasonable to say that the way he behave given the cirstances and stress i was under was unforgivable and very cruel..What do you think?
