Take the time you need to work things out for yourself. If you're getting feedback here that is unhelpful for you, let people know. You have the right to process this at the pace that feels right to you and in the way that feels right to you.
Everyone here has that right on their journey.
If the people trying to help you here are overstepping the mark and just criticising you, it's okay to set a boundary for yourself.
This is your journey and only you can work out what you need to do.
Sure, there are a lot of "patterns" to these relationships and those that have been in them before can be impatient for others to "move forward", but you will have to work it out for yourself, to a large degree.
It can be good to hear critical insights, but being criticised a lot is rarely helpful in working out the right way forward.
Be clear about what support you want and what is helping you, so people can offer you more of that.
you guys don't know me or her and are so far off the mark
If you feel people aren't hearing you or are invalidating your experience, let them know.
You're absolutely right that you are the only one here that knows your situation first hand.
I know breakups are inherently confusing, so it might be hard to clearly express your thoughts about this stuff at all.
Your feelings may be all over the place and contradicting each other from day to day.
Anyone who's ever been through a painful breakup knows this and can relate.
So take your time to work out what's going on and what you would like support with.
Not my fault that I may have BPD.
Can you clarify whether you mean Borderline Personality Disorder with BPD? As far as I'm aware that's the official abbreviation. But I know some ppl use "BPD" as an abbreviation for Bi-Polar Depression too.
If you mean borderline, can I ask if you are getting help/ therapy for this?
I wonder how borderline impacts your relationships? As far as I'm aware it has a huge impact on relationships, much bigger than even the impact PTSD has on relationships.
