Hi yummymum,
I agree with all the replies you have had, do not chase after this man, it is the way he is controlling you.
I know it sounds 'cheesy' but there is a really good song you should listen to;
I Need a Little Time, by The Beautiful South (they had loads of hits about 10 years ago, most famously Perfect 10)
Basically he has his time to go off and do his own thing, whilst you 'hold the fort' and welcome him back.......however, one day you decide that the time away from him is more enjoyable and you now need 'a little time' to decide what you want.
Don't try to shock him into coming back to you, start deciding how your life would be better without his childish tantrums.
I've read other threads of yours and answers you've given, trust me, you are worth more.
Either way I wish you well.
