And a new man would hum,
And if I mentioned his name I would upset my Mum.

I thought that this meant your mom was cheating and she felt guilty if you talked of her lover who would show up after your dad went to work. But the end makes it sound like your dad left and was gone forever.
I think the pronoun usage in the lines above are confusing and I don't know who you are talking about. this coinfusion muddies up the meaning of your poem.
