I may be way off the mark here but I just wondered what would happen if you calmly ask H the questions about what he is saying(re convo you just related) at the time instead of letting it fester than getting the awlful urge to phone or text him and it resulting in an argument. Of course if you ask at the time he may not reply or he may tell a lie but at least what's in your head will be out and you will not then have to let it grow so big that you explode or very nearly. It all sounds too simple when I type it but I guess there is a reason you don't call him about it at the time. Ignorance is bliss so "they" say but "they" also say knowledge is power---hmmmm. Stay strong it gets easier.
