Asked on a date whilst still being pesteres by my toxic/abusive ex

TLDR:

I (24F) recently left a very toxic, slightly abusive relationship. He (23TM) keeps trying to get back with me and refusing to give me space. I've been talking online to (27M) and he wants to meet up, I'd really like to, but my anxiety is going insane.

So some background on my previous relationship:

I (24F) was with him (23TM) for 7 years. We met as young teens. He grew up in foster care, so he's been intertwined with and almost practically living with my family the entire time. During the good times we had he was incredibly sweet and supportive.

During the 4th year of us being together things got really toxic. We started to constantly argue. By the 6th year of our relationship, during an argument, he poured a drink over my head, pushed me to the floor and kicked me. I stupidly took him back.

He then pushed me down my small set of front steps.

My parents never stepped in because they believe me shouting during arguments means I'm just as bad as him.

I finally spoke to a friend, and left him after realising how serious things were. After telling him I was done he sent me 100+ emails, 50+ no caller id calls, god knows how many social media and whatsapp messages. He also sends £2000 saying he wouldn't need it anymore as he was taking his own life. I sent the money back and offered him support being scared for his own wellbeing and in all honesty, my own too.

It's been 4 months. He's still coming over basically every single day but now sleeps in his rented room around 20 minutes from here. He walks home at night. He constantly guilts me for leaving whilst here. When I ask him for space, he brings my parents into it, threatens his own life or asks to get his things and then refuses to leave. He plans days out and does the same thing if I refuse to go. He forces gifts on me, and attempts to pressure me into sex and getting back together but I stand firm. I acknowledge him trying but he's forcing himself on me and it's only validated my leaving.

The only time I get peace is when I get to see or stay over a friend's. Even then my parents track my location and he constantly texts.

For around 3 weeks, I've been talking to someone new (27M) online things have been going pretty well but he wants to meet next Friday and I have so many worries.

1. He knows my ex is still bothing me, but not how much. He has a stalker ex and the police had to get involved, idk if that will make him more or less understanding. I've told him I have a ton of baggage, one of which being a currently active crazy ex, but he doesn't know how bad stuff is.

2. He's extremely intelligent, successful and attractive...I look like a loser compared to him, I don't feel good enough at all.

3. My ex doesn't know I'm going on this date, I'm saying I'm visiting a friend out of town, but I'm still so scared of him finding out, flipping out and embarrassing me.

4. My parents tracking my location. Since I've become a "free woman" they've even called the police on me...I was hungover at a friends house. They also tell my ex what I'm doing.

5. I haven't really been on a first date before and I have trauma with meeting people irl from online. I'm nervous. What if he doesn't even like me in person and all of this worrying was for nothing? What if I get stood up? What if it's secretly my ex catfishing me? What if things go too well and we go back to his and he sees and hates my constellation of butt pimples? Idk, I'm just totally and completely freaking out.

also sock puppet because he has my Reddit
