How do I handle the situation?

My boyfriend and I have been dating for 5 years. We have been through a lot together, moved country, changed job. Bought a dog together. He really is supportive and loving. The only issue is his ex gf (who he dated for 7 years).
Although she has already had three different relationships during this time, it feels like she never got over it (as he broke up with her after he found out she cheated). Luckily he wants nothing to do with her but she always tries to stick around/disturb in weird ways.
For example when she found out that we started dating, she tried and successfully worked her way back into his inner circle- they had similar friends (as they dated for so long). She turned them against us - with an attempt to isolate him and make it look like it was my fault. Before he started dating me, she completely stopped talking to his inner circle and didn’t want anything to do them.
When we visited his parents on vacation we bumped into her and her new boyfriend. She said hello but then proceeded to ignore us and only talk to his parents. Hugging them and reminiscing on the memories she had with them (in front of me and her new bf) she even said ‘what wonderful times, I really miss it and all the things we did together’ - after 7 years!! My bf parents didn’t help the situation as they kept asking her questions about her family and I could see she was so happy that they were giving her attention. I could tell she wanted to prove to me that’s she knew them so much better/had a better connection with them/one up me - she didn’t want to leave! We were having dinner at a restaurant and she stood there for 10 mins saying how great she is doing, etc. Her current bf didn’t speak the language so he had no idea what was going on. It was so uncomfortable and I felt bad. I know that his parents were just trying to be friendly but it was almost too friendly.
The weird thing was that his dad said that she had seen her a couple weeks ago and kept talking to him. Like if she were trying to re-establish a relationship.

My boyfriend was also extremely annoyed as after so many years she can’t let things go. We talked about it after but he just tells me to let it go.

Dealing with a situation where your boyfriends ex is still causing disturbances can be challenging, but it's important to handle it in a calm and rational manner. Here are some steps you can consider taking:

Communicate with your boyfriend: Talk to your boyfriend about how he feels about the situation and what he would like to do about it. Make sure to listen to his concerns and feelings before taking any action.

Set boundaries: Encourage your boyfriend to set clear boundaries with his ex. This may involve blocking her on social media, changing his phone number, or having a direct conversation with her about respecting his space.

Document the disturbances: Keep a record of any disturbing behavior from the ex, such as harassing messages or unwanted contact. This documentation may be useful if legal action becomes necessary.

Consider legal options: If the disturbances escalate or become threatening, it may be necessary to involve law enforcement.
Encourage your boyfriend to file a police report if he feels unsafe.

Support your boyfriend: Offer emotional support to your boyfriend during this difficult time. Let him know that you are there for him and that you will help him navigate the situation.

Seek professional help: If the situation becomes too overwhelming, consider seeking the help of a therapist or counselor to help both of you cope with the stress and anxiety caused by the disturbances.

Remember that every situation is unique, and it's important to handle it with care and sensitivity. Encourage open communication with your boyfriend work together to find a solution that works best for both of you.
