My hubby travels a lot for work, how do we keep our marriage strong other than doing regular skype call?

Communication is key, so regular skype calls are great. Other than that, surprise each other during the times you are together. Or simply spending quality time together and doing activities you both enjoy will help keep things fun and interesting. My brother-in-law also often has to travel as well. Everywhere he goes, he will pick up a small gift for my sister. It may not be anything special. Sometimes, it's just an interesting mug or a simple ear stud. However, this shows that he is always thinking of her and she really appreciates the gesture. At the end of the day, I feel that it really boils down to putting in the effort to make time for each other. Even if it is just the regular skype calls, that may be good enough. :)

I did it for one year. Having the commitment to meet face to face in a schedule holiday or visits is a must
