Why is she contacting him now?

[Tinseltangle]

Boyfriend hasnt seen or spoken to his ex for 3 years, there is no reason for them to have any contact. Today she called out of the blue and asked him to go to the chemist as she was ill. He duly went and dropped the meds off at her home.
Why is she contacting him now?

Because they are in regular contact.

I think there has been contact prior to this, you wouldn't randomly reach out after 3 years to an ex to collect some from the chemist. How long did he take to drop the meds off?

Perhaps they are in regular contact or she had no one else to turn to.

I was at work when it happened, so I have no idea how long he took. He called and told me about it, otherwise i would never have even known.
It just doesnt sit right with me, and the suggestions that they may have had previous contact make sense. I know she has called his mum several times but she has not answered the calls.

Maybe she really had no one else to help her?

Because they are in regular contact.

Absolutely this.

He called and told me about it, otherwise i would never have even known.

Somebody you know saw him there today, I reckon, so he’s getting in first to convince you it was innocent …

Yeah they're still seeing one another.
You don't call your ex that you haven't seen in 3 years to ask him to go to the chemist for you.

Even if you were a hermit and you didn't know anyone else, you'd just stay in bed till you were better.

Well, unless it's thrush (and you have broken your ankle and can't drive or something). Because let's face it, when your fanny is on fire, you'd even call your worst enemy if you think they would help haha.

Pp is probably right though, he has been up to no good and someone saw them together so he needed an excuse incase that person told you.

Follow your gut instinct.

How did the relationship end? I could say that if they ended on a good note and she was really struggling and he was the only person she could think of, then she would ask him in an emergency.

Maybe she was desperate. Is you dp a generally helpful man and thought he would help her out?

At least he told you. If it was fishy, he probably wouldn’t have said anything (unless spotted). Or maybe he told you because he thought it was strange also.

Can you look on his phone to see if there is any evidence of regular contact?

He thinks someone saw him arrive at her house, it’s a preemptive cover up

Check his location history on his iPhone. It will tell you how many times he visited her address

I agree.

Or she has threatened to tell you about their relationship so this is his backup plan in case she ever does. He might start telling your stories about how she’s crazy, is stalking him and harassing his family because she wants him back. Or that she’s jealous of the beautiful thing than he and you share and wants to destroy it. Etc etc

If she was that desperate, she'd ask a neighbour, work colleague - not your ex from 3 yrs ago who you've had no contact with since! Just doesn't seem logical. He's lying.
