No you are spot on with everything, not a bit wrong in fact. Both of them like their independence and yet are simultaneously loyal where it counts, which I suppose is why it has been able to work so well for so long, despite personalities which are rather different in many other respects. My mother is probably more inclined to jealousy than my father but she has always been the dominant one and if she feels jealous she is paradoxically more likely to push people away rather than cling to them (something I seem to have inherited). My dad is just not a jealous type at all, which I think is a very sag thing... To give an example, a drunk male friend of theirs recently started sucking my mum's thumb at some party and my dad just thought it was hilarious and that he's a "great guy". Similarly, years ago some other male friend of theirs hit on my mum in private and said something to the effect of "I think it's okay for couples to have a bit on the side. What people don't know can't hurt them"... When my dad heard about this he just sort of shrugged and said "ah, he's a funny one". Either this is intense denial on his part or he just feels very assured that my mum wouldn't do such a thing - maybe a bit of both.
Yeah I think dad's loyalty is from the cappie mars, and maybe that scorp venus too (which is conjunct my mum's mars and rising). Funny you mention Brad Pitt - my dad's sun and rising are conjunct Brad's (my ascendant is also *exactly* conjunct Brad's asc), and my dad has often commented on what a ruggedly handsome man Brad is
My dad was pretty good looking when he was young, yeah, though apparently largely unaware of it.
LOLOLOLOLOLOLOL OMG your mom is like the extreme version of me! i'm not a jealous person, but when i sense that there's the possibility of rejection, i will be the first one to oppose vocally. i will push, kick, shove others away first because it would really pi$$ me off to allow myself to be rejected. i don't know if your mom feels that way, but it's quite possible being that she has scorpio rising and i have pluto in the 1st.
now, as for your parents' fidelity, i won't comment on it because i don't know them. however, i will draw up a similar glimpse from my own relationship files. the first person i was with after my divorce was with a sagittarius capricorn sagittarius and it was really fun... for the most part. the other part that was not-so-fun was because of the cap moon being cold and then my pisces moon gets fed up and left him for good. the thing was, we were really wrapped up in each other. like your father, ted (his name) had an earth mars, virgo... in the 10th house! he had no troubles being the best at everything he did, no issues racking up $$$ (a lot of it was investments). he was tall (6'2"), thin and toned, manly, handsome (neptune on asc), and did everything i wanted. it sorta bothered me a bit, but he was willing to do everything that i tell him to do. he took care of me, didn't care if i worked or didn't work. he allowed me to do everything i wanted and i allowed him a lot of freedom as well. he always paid for everything, never thought about not having money, we just kept spending money like there's no tomorrow. we were quite inseparable and cried when we had to part (as odd as you may think with opposite signs). he had carried a torch for me for years and even though at the time i was with my leo, he tried to barge in numerous times and steal me LOL much to the leo's anger and jealousy! ted's venus is in late capricorn which forms a close trine to my late taurus mars. the men that i've been involved with that go nuts for me have cap venus trine my taurus mars (seems to be the right formula for me). anyway, much to say the least, we had a very explosive romance and we kinda moved in together very fast because he was talking marriage and kids and was really excited about us. he had never been excited about anyone but me, i was the light at the end of his tunnel, i was his ideal of the woman for him.
well i brought all that up because in many ways, i can understand your dad's apparent lack of "awareness." i don't think he's really unaware, i think that he really is super close to your mom and although they've had 40 years together, it may not feel that long to him and he doesn't want to think about troubles that could endanger that feeling of "forever" with the woman that really rocked his world (his scorpio venus conj your mom's scorpio mars). i remember ted told me, "please, don't ever leave me. if i'm stupid, just beat me up, but don't ever leave me." instead of beating him up, i chose to leave him (unlike your mom, i have libra rising which HATES confrontations). looking back on things, i knew i missed out on a life with ted that sounds so very similar to your parents'.
