June had a bee in her bonnet about them living together at Goldhanger bringing shame on the family. There's every likelihood that June had mentioned being married before living together and because of that Jeremy would have felt as though he was being pushed into something that he felt he wasn't ready for and this could quite possibly have been a reason that the relationship was fizzling out.
What man of 24 would want to take that order from their mother ? Maybe Jeremy had been too ashamed to tell JM of his mother's wishes ? Whereas,you'd have JM tugging at one end and the voice of his mother in his ear talking about immorality.
Talk about being between the devil and the deep blue sea.
