Do you think you have the ability to make your lover live happily ?

That's the thing for you both. I think happiness is not the thing who can give you ,because it's not a gift ,but the thing who can create with you . so why so many couples they have not many money but they can also very happy ? for they are toghter and hardly work for their conjunct happiness,In my eyes that's the happiness they bring to the beloved one.Do you agree with me ?

I think the thing is you both need to continue to work and make your relationship work. One person can't make the other happy. It takes two people not one to carry a relationship. Best of luck to you.
