Mum was diagnosed with alzheimers about 6 months ago. She had been living on and off with her partner for about 5 years until he moved out again shortly after this diagnosis (back to his wife).
They had a complicated relationship as he had left his wife for her (old flames reunited by a certain website). They also lived in effect under the same roof as my Dad (they split house into 2 'flats') he was never happy with that arrangement but it suited my Mum / Dad who were incredibly amicable after they split.
Just after he moved out, my Mum / Dad agreed to sell their property at which point the ex (who still keeps up regular contact with her telling her he loves her etc etc and making constant excuses about why he's not with her - mainly medically based) decides if that happens he will move back in with Mum.
He is now trying to put money into the property (he wont admit how much but we've seen something that implies a 1/5) that we have all found for Mum and agree would be ideal for her.
We have no idea if he has the money, we have no idea if his wife know's his intentions and all in all it's all getting nasty - he's very abusive to her on the phone, wont answer our calls and the final straw was demanding she get a divorce and change her name. (yet he's not divorced)
We are well aware he is a control freak and it's not been an easy 5 years.
We don't believe he is going to leave his family again (his children wouldn't let him have contact with his grandchildren after he left and he's just re-established this) we also don't expect him (or want him) to become a carer for our Mum. But, he wont give anyone a straight answer - inc. her solicitor.
Mum has, what I would call, reasonable assets (aside from the abilty to buy the half million pound + house outright) and we can't help but think all his messing around isn't genuine and he's up to something ???
Sorry this is long winded and probably v.confusing but the gist is - are we being paranoid is he trying to take advantage of our vulnerable Mum ?
