UPDATE NUMBER 2 Trigger warning, need some clarity for my friend

Don't even know where to start with this. My friend and her partner had been together for 10 years, since the age of 17. They haven't ever really had the best relationship but she loved him and they were ok. Out of nowhere about 2 months ago he told her he needed a break but really what he was saying was that they were over. He had got her into an unreal amount of debt, her home now had to be sold and she had no idea what was happening.

A week later he moved in with a woman he met at work 2 weeks before their relationship ended. My friend tried to end her life, she couldn't face losing everything and luckily she survived it and we got her help.

He was living with this woman now so between me and her family we got the house (that he had run into the ground) up to scratch so it could be sold. We packed up all his things because he couldn't be arsed and moved them all to his nan's house. In the mean time he heard about her suicide attempt and acted like he was concerned for all of 5 minutes then told her she needed to move on with her life and get over it. He told her everything that him and his new gf were up to, going on dates, sleeping together etc. He fully messed with her head.

2 days ago he turned up at her house at 3am and told her he had nowhere to go and that his new gf was abusing him physically and mentally. He had a video to prove it of her hitting him etc. But this man is a pathological liar and I can imagine there is a lot more to it than what he is telling her. He's lied from the day I met him and always gets caught out in the end so I can't see this being any different. Don't get me wrong I don't condone her hitting him what so ever, but I know this man well and he has falsely played the victim way too many times to be believed anymore. He brought back some of his things, dumped them in the newly done up house and slept on the couch. Since then he's begged my friend to let him back and even though she has said she needs time he's not respecting it and taking advantage of her vulnerable state. He's kissing her like nothing's wrong as he's leaving the house, he took her money off the side without even asking because he needed parking money. He's telling her all about the messages this girl is sending him as though it's something they are both over it already. She is that confused and it's all happened so quick that she can't see what's happening around her. I told her about this app and she asked me to post what's going on. She needs to hear the blunt truth whatever it may be and I've told her the women on here are great at that. So thoughts anyone? Have you been through anything similar, how has it turned out for you?

UPDATE

thank you all for being so honest and to the point. She really needs to hear these things right now. Please keep going!

UPDATE

he left again to nobody's surprise. Begged her for a week to take him back, she agrees with some time and he dropped her like a sack of shit again because 'it's unfair to her and she deserves better' when really it's because he's getting back together with he other girl. Biggest shit storm I've ever seen in my life. At least she's starting to realise who he really is and is now starting to see that she doesn't want him anymore either
