I am 37 and have recently started seeing a 51 year old man. We have an amazing amount in common and I think he's completely amazing. He is a very caring person and makes me feel very treasured. I am coming out of a broken marriage and have young DC so am wary. He has had various long-term relationships / been engaged in the past but has not been married or had a family.
He is very keen for me to move in and has mentioned marriage (as proof of commitment rather than to put pressure on me).
I am head over heels right now but also a bit scared by the age gap! I feel like it will be magnified as we get older? Also he has some health issues such as high BP, asthma, old sports injuries (he used to run / train a lot, but less now) etc whereas I have the constitution of a moorland pony.
Should I be worrying about the far-off future like this or just enjoying now?
Does this age gap seem too wide?
