Jealous friend!

I met an A guy for 4 days nonstop, we had fun. He was cute, sweet, gentle and really friendly guy. Then B guy i have known for 4 years asked me whom i met and i told him. He knew the A guy and started talking **it to Him in grindr and attached me in those messages with him. The A guy got mad and started texting me furiously and then he blocked me on everything :’( I got so mad i left the car i was driving with B guy and walked home in snowstorm. I cant even ask for forgiveness from the A guy anywhere because he blocked me everywhere.. I am really broken because the A guy wanted to try more seriously and i have never met such a nice and loveable guy before! :( ..
