hey buddy here is your answer...

Aniline has higher pKb thanmethylamine because methylamine is more acidic than aniline as in methylamine delocalistion of lone pair of electrons belonging to nitrogen occurs as a result resonance structures are formed which increase the acidic character of methylamine as a result it has lesser pKb value.

The hydrogen bonding would necessarily require that the lone pair of electrons go 'out of conjugation' with the ring system, and hence there can be no donation of electron density via pi-effects as in the para-phenylenediamine case.
