No you are not too old however this last year has affected everyone's mental health (mine included) and nothing is normal so maybe not the best time to make major decisions unless you can discount the lockdown effect. Me - I am remembering what I was like before I got married and since and I am a different person - used to be spontaneous and have fun and go out with friends and work colleagues and now (even before covid) never go out even for coffee unless I suggest it, meal rarely then we go home for coffee - why? Since lockdown - lots of childcare as childminder shielding and DD2 in our bubble but DH has become weird - we share bottle of wine on a Friday evening - now he puts it in fridge on Thursday evening very super organised. He listens in when I'm on phone to my mother, brother, DC then asks what they have been saying? Resorted to phoning on mobile sometimes as he can't listen in. It puts me off having a normal conversation if someone is listening. He looks up my messages. He is upset when I don't give an accurate plan of what I am doing - collecting DD2 &DGS2, taking her to work, going to shops to buy bread and milk, going to DM (am carer) to check her fridge, meter readings, alarms and any issues and that she is ok. But makes passive aggressive comments on everything I tell him - why? Checks what I have put in food recycling and disbelieves me! I am 64 and will put whatever I want in the food recycling and it is beyond weird to listen to what I scrape off plates. On the other hand I don't think he thinks this is not normal or coercive. He has mostly a brilliant relationship with DGC and supportive of our DC problems though complains to me. He doesn't take my criticisms or talking about it at all well so I try not to. Sometimes I literally bang my head, pull my hair, thump things. Leave the rest to your imagination. I think he is on ASD spectrum maybe. Anyway it has got worse for me during the pandemic and I don't feel I can fully trust what I feel - some things yes, others probably just wistful for the past. But apart from our family we have little in common. Maybe I'm just wrong. So I guess you need to ask yourself if lockdown has affected you both or is it a longer ongoing issue. If it has perhaps wait a while and monitor, if not the make preparations.
