Attraction in the sense of wanting arm candy- you prize being with someone who has certain physical features -is different from chemistry -to me chemistry is essential. And often is related to what someone looks like but not always and not always to any real extent. My husband and I are 57. We are not hot looking.
Last night we were at a dinner party and - unusually -we were able to sit as a couple while our teenage son sat at the "teenager table" instead of with us -so it felt like a date to us. We held hands for part of the time laughed in a way that with our son would not have been the same sort of couple laughter, etc.
No I didn't feel like sneaking upstairs to have sex with him but after knowing him since the mid 90s and being together and married this time over 15 years I still think that sense of clicking/attraction/chemistry is essential- it's the glue that keeps our marriage healthy. We had intense zazaza stuff when we first got back together and many many times throughout our "courtship" but because we're confident in the core of attraction and chemistry to me anyway you don't have to feel that level of intensity to know you're with the right person romantically (yes, at times I still feel that way and I can totally go back to that time in my head and know it was real and is real) and you don't have to think "wow she's hot!!!" to feel chemistry .
Certainly being repulsed is no good but feeling that overall chemistry doesn't require a focus on physical features -more like -to me - a "noticing" like noticing your partner is attractive looking, noticing his eyes, and sure I don't mind that at my age I'm physically fit and slim and cute enough and sure it's nice when he compliments me (and I do the same).
Be brutally honest with yourself - how important are physical features to you - and consider in a long term relationship what if she loses those particular physical features -maybe gets a bit flabbier, doesn't lose baby weight for a few years, gets age spots or wrinkles and isn't into botox or potions. It's totally fine if you are a person who is very focused on certain physical features just like some people are very focused on certain sexual positions or ways of having sex -but your priorities will help you pick better and always be open to reevaluating your priorities.
This woman deserves someone who thinks she's all that - and you don't -let her go. IMHO.
