Am I a rebound?

Tl;Dr: Ex broke up with me after 4 months, mentions she bumped in to her ex and they chat a bit. Says she has no feelings for ex and does not want to get back but somehow thinks of him at times. Had dinner with her & friends, ex calls her, i ask if she wants to get back with ex, she says I dont know…maybe…we’ll see. Was I the rebound after all?

As the title says I’m questioning whether I’m the rebound. Just last week my ex of 4 months broke up with me because I made mistakes along the way such as being needy and not respecting her at times which made her lose trust and feelings for me which was all warranted I get that part. However, she mentions that she bumped into her ex a few days ago and chatted a bit and that she was happy to see him fine and that there were times that he drifts into her head during our relationship. A quick backstory to this was that her ex bf (together for 2 years) helped her settle in Australia and gave her an Australian life (taught her English, some finance, accommodation), so I understand he was a huge impact to her life. Prior to starting the relationship I did ask her if she still had feelings for her ex to which she says she wont get back with him and she doesn’t have feelings for him after everything that happened. On the break up night she clarified that she does not want to go back to her ex but feels that she needs to take care of him like his mum.

However, after dinner with her and her friends yesterday, i was walking her to the station to which her phone starts ringing and she promptly rejects, the phone rings almost immediately again to which I tell her to pick up and I hear her say the lines of; I finished dinner with my friends, I’m heading back home on the train now, I’ll call you back later. I wish I didn’t ask but I asked who it was and she said it was her ex bf. I proceeded to ask if she started talking first or he did to which she said it was him. Out of slight jealousy I asked whether she wants to get back with her ex and she answered, I’m not sure…maybe…we’ll see in the future. I didn’t overreact or anything, but was just confused and questioning myself whether I was the rebound the whole time. I understand what caused the breakup, but I don’t understand why she would say those things before.

In addition, we agreed to go on a road trip with friends and I have to drive her as well because that was planned initially. What to do during the car ride?

So questions are:

Was I the rebound for her ex?

Would it be reasonable to let it pan out and pursue her again after some time?

It takes a long time to get over a 2 year relationship, so I don’t think she was ready to date you with a clear head. You are in danger of being friend zoned if you’re still meeting up and going on a road trip, even while the other guy is contacting her and she’s “not sure” she would go back to him, so it sounds like she’s considering it.

You made mistakes while in your short 4 month relationship and she chose to break up because she wasn’t happy with you. Apparently she and her ex got along better because their relationship lasted a lot longer!

I think you should break all contact so she can think about what or who she wants…
