If he profess to love you then he should really have time for you. Love is meant to be sacrificial and not unyielding. Why not try and pay him a visit, at least he shouldn't be working 24/7 for the whole week? Making marriage plans with someone you are doubtful of, is like building castle in the air, LOOK before you finally LEAP, Shalom!!!

Anything done without God would face more challenges (irrespective of your religion), I'm not saying God-founded marriage is not void of challenges but you need to LOVE your spouse, STAND BY (for better for worse), be COMMITTED to each other and lastly PRAY for another, Marriage is not bed of roses. I think marital challenges would be solved based on my views.

Well, too me, my opinion to your issue is that, talk to any close relative of yours in other to disclose your intentions, maybe through then, your mother might yield to your consent. you have to also prayerfully seek God's face since you say and I quote, "I'm a christian", God will see you through your marital relationship.
