Is this really witchcraft?

So my ex and I were best friends throughout our marriage. Things were not perfect but we were good, we always got thru our obstacles. 2 years ago he came and wanted to separate. I was shocked. Now his mom, who is more spiritual or in tune with this kind of stuff swears it's black magic. Her reasons are this: - my ex literally became a complete different person overnight. I really can't explain fully how he changed, but like he wouldnt even return a greeting from me the day after he told me we shud separate. - out of nowhere he meets this lady, she's 10yrs older than him, which is fine, but he's a very religious person and she's of no religion apparently. - he pretty much reduces communication with his parents down to a minimum. This is a guy that wud speak to them everyday via chats or calls to the point they constantly have to call to check on him. - ever since we got together, my period stopped but as soon as we separated it came back. - now he's seeing stuff and his gf keeps telling him things that there's no way she knows. Like really intimate stuff from our wedding night, despite the fact that the wedding was 10yrs ago, in a different continent which she isn't from and isn't living there.There's a whole bunch of other stuff, His mom thinks his gf did a love spell on him bcoz he was like crazy about her and now it's starting to wear off, bcoz he's actually saying he's scared of her. But he doesn't want to go into the details. She also thinks someone did a spell on me to prevent me from having kids and then a spell to destroy our marriage.What do you guys think? Is it possible, if so how does one break such spells? via /r/witchcraft https://ift.tt/3iuU4v3
