1. I miss them, do they miss me?
It's a given that in any close relationship where you are apart, you are bound to miss them; but the question is do they miss you just as much? If they say they do, then you should trust that they do. Unless you know something is wrong, you shouldn't think otherwise - stay positive!
2. What if someone better comes along and they prefer them to me?
Again, trust is a key factor here. You should trust that the other person will not stray and after all, they are still with you, aren't they?
3. When will we next see each other?
To solve this issue, you should make plans to meet each other before you have time to worry about it!
4. Is this working?
That is for you both to figure out. If one of you is unhappy about something, you should discuss it and solve the dilemma together. This will in essence bring you closer together once the problem is fixed, as it shows you both want to work together to make the relationship work.
5. Are they coping well with the distance?
Talk to them about the distance in your relationship and how they feel about it. Listen, show you care about them and that this matter is important to you.
6. Am I coping well with the distance?
Take time out to figure out your feelings too. If you are unhappy, it may be helpful to talk to your partner or a close friend or family member about this. Talking about the situation will relieve you and take a weight off your shoulders if you have been mulling it over for a while.
7. I don't want to lose them.
If you don't want to lose them, then don't let them go. Make sure you keep in touch and that you are both happy. After all, it takes two to Tango.
