I could see my husband expressing concern over where or how I might be traveling, or if I worked in a dangerous area, but he trusts my judgement. I'd feel the same way about him, and we would talk about it.
It concerns me that you are putting such conversations on the back burner because it's not relevant to you now. I'm sure you see how when subjects you've choosen to ignore come back up (and they will), it will be more difficult.
If you are planning on marrying, things that are important to each of you need to be brought up and decided upon before the marriage.
I'm very independant too Mall12, and I've been married 23 years. I have never dealt well with clingy, "cute" behavior, which is the basis ususally for this "I miss you so much" stuff.
If you are independant, then surely you won't mind not marrying this particular person until you find someone more suitable.
You might want to find someone who is also independant, and who you will be an equal partner with.
