Give him some space. Set ur boundaries and stick to them. If he's acting like a child, then let him, dont let it affect YOU tho. Get out, go to another room. NOt a lot of info on ur sitch so not sure what else to tell you. I can tell you one thing tho, act as if it doesnt bother you anymore. Pretend you dont care. If he;s whistling to irk you, then dont let it. Sounds like he doesnt want to talk. SO dont. Let him stew. Go about ur business. GAL , look at yourself and any 180's you can do. Take care of your family.
Very sound advise.
