Why would he mention this on his birthday, and not give my money back?

This person called my partner to tell him they day of his birthday if he wanted to purchase some “antiques” that my partner likes as well as her partner that died in an accident liked as well.

This woman got in the middle of my relationship 5-6 years ago and he apparently did not want to erase her number they were just “business” friends,(she sold him his house, our house) so I put my foot down and drawed a straight line saying: if ypu keep this up, it’s over, so he got away from her , no more messages etc, but after a while during December of Covid she came back inviting him to the gym.

Apparently she married a rich man, he died recently in a bad accident and she coincidentally calls my partner on his birthday to ask him if he would like to buy some of her ex husband articles gadgets, that my partner likes as well.

Im just in awee that my partner has the audacity to even mention this situation on his birthday to ME, that this girls husband dies and she calls to tell him and bla bla, honestly who cares? I truly feel bad for her husband that died, I dont give a dam about her or her feelings, shes a bad person.

Maybe i’m wrong but i’m getting a feeling this is gaslighting for something that hes planning , either hes looking for excuses to break up, cause iI got so disappointed after he told me this that inspite of it beingbhis birthday I dressed and went out to get some fresh air and distract my mind , even my chest began to hurt.

So when I returned he was sleeping and was like that all night (he was tired coming from his job) but I though he would say lets go do something for my birthday, so almost about 12 at midnight he wakes up, I was explaining something to him about our pup, and he began getting all touchy and giggly, I was not in the mood, so he got up mad and confronted me saying that why was I acting like that, that if the reason is that I am not attracted to him anymore he gave me a long manipulative controlling speech( cause I feel hes a manipulator).

So he said think about it because I will not beg you to be intimate with me blah blah, you have to think if you want to be with me and he went on until he went to the other room.

Another thing is he owes me money I lended him when he had a hardship had lost his job etc  but yet he decides to give his mom money first( cause supposedly she has some situation in her country that she needs to settle, this woman I dislike I feel shes taking his money to bother me and to screw me) He started a new job 3 months ago, good pay plus he rent 3 spaces yet he never has money, it’s always something going on with him, hes paying  little by little, i’m just afraid I wont see my money back and I realky need it.

What do you think I should do in these teo different situations, cause i’m mad.
