All hope is lost/help

[Evie]

H dropped bombshell in May, ILYBNIL with you confession. H has slept on sofa; we have been on holiday, H moved back into the bed, we have made love a few times. I read DB and applied 180 behaviour. i have given him space, not pressured him to talk, massaged his ego, done all the giving, and him all the taking, i was learning to be patient as teh book says. H typical caveman but much worse. 2 boys aged 3 & 7. H dropped bombshell 2 weeks ago that his feelings are unchanged and is looking for a place to live and cannot give me a reason for not loving me, he just wants it to end amicably and be best mates! Any advice
