I have received a marriage proposal from a pious boy.

Answer

Nowadays „piety‟ is a rarity. Genuine Taqwa is not to be found. An outward display of religiosity is not piety. Every Muslim, whether faasiq or faajir, is obliged to adopt outward piety which consists of Islamic dress, beard, performing regular Salaat and speaking with a smile. But these outward displays whilst important and imperative, are not the sum total of piety (Taqwa). The seat of genuine piety is the Heart, and this is lacking in Tablighis.

If you will be able to be at peace with a husband going on 40 day and 1 year jaunts; with a man who will accord greater concern to his jamaati activities than to the obligations of his family, then perhaps there will be compatibility. Reflect deeply, and make no hasty decision. A mistake in this domain will bring misery lifelong.
