What an interesting thread I have missed! I have very much enjoyed reading every page. I'll grab at this one...and to stay completely on topic, I'll answer the original questions:
What are the features you look for in a sentimental partner?
Firstly, I like the phrase "sentimental partner". Secondly, I will say that in recent years, wisdom has taught me that you usually find someone when you are not looking. I think some members on this forum should heed that advice! ;-) I'll say what I like: BRAINS. Nothing turns me off more than a man who can't articulate one intelligent thought. Going with that, for him to be a good conversationalist is key. Goals in life are imperative. I'm a bit older than a lot of you here, so for me it's important that a guy doesn't live in his mom's basement and can take care of himself. Thoughtful and affectionate. My life centers around music, meaning, I am a musician as well as a huge fan of it, so that really is important in a mate. Most of my spare time revolves around music, so it really wouldn't work for me if my partner didn't share the same passion. I'll stop here for now to avoid endless rambling...
Assuming that one can't have everything, do you place great stock in moral qualities such as fidelity, ability to withstand adversities etc. at the expense of the degree of passion and affection that the person spontaneously elicits in you?
Though some relationships do mirror perfection, yes, the reality is that you can't have everything. This is where compromise comes into play for me. Morals are important, for sure.
Would you rather have only one partner for your life or several? In the latter case, do you think each of them should be a synthesis of what you like or would you prefer to have different people for different seasons of life?
Well, considering I already have had more than one partner in my life, I guess having one exclusively doesn't really apply? I dunno. I guess what I'll say here is that if I found someone who I really connected with, of course my intent would be to spend the rest of my life with that person. If things went sour, of course I would have no problems moving on to someone else. I think it's natural to want different types of people in different stages of your life. Certain things remain the same, but your tastes in other areas to change and progress.
Why do you think you're attracted to the qualities you're attracted to? Do they fit in your personal history somehow? Do they reflect something that you learnt from/see in your parents? Or opposite to that? Etc.
I can't seem to turn the bold lettering off for this one. Ah well! These days, I blame my taste in music nerds on my father, LOL. My dad raised me on rock and roll, so it has kind of been my environment my whole life. Other qualities I desire are a mixture of things, what I've seen in my parents that I liked/didn't like,and things that I have experienced in other relationships that I have learned from.
