Following up from my other post

The first is hard for me, I just don't know how to let go of being in love with her

That one's easy. While many switch from singing the praises of their ex to demonizing them when they let go--it's also okay to continue to love. Today I say, "I love you, my ex. May you find the happiness solo or with another that you didn't find with me." This is especially true when there wasn't an OM/OW before BD. Love wishes the best for another, even if that path takes them away from you.

AND when she send me text messages outside of picture of our daughter like this morning I get so confused: (Picture of a vintage sweater with the text "Mom found this baller sweater I used to wear 😂"

This is where you decide if you want to be friends. If no, stop texting pics. Even if you want to eventually be friends, a brief period (e.g., 12-24 months) of disconnecting is probably healthy for your detachment. I'd pick a period long enough you're not looking forward to the end or hoping for some change when it does.

now I know of someone that wants to date her - which is really getting me spiraling

The real question is if she wants to date. There are always other people if one wants them.

Lastly, I've learned so much over the past 2 months about myself and relationships.

Yes! Breakups are catalysts for change in our lives.

Focus 100% on me (and not really mentioning anything about he

Sounds great. Maybe, focus 90% on you? It's good to acknowledge and process what you're feeling.

I'm learning to start to envision a love that I want to create in the future, irregardless of who it is with.

I'm about to start working on that. What does your vision look like, and does your ex match it?

The part about her traveling more often and allowing her to take my daughter for long extended periods of time hurts (missing my daughter) AND I'm willing to do it because I care about the connection between her mom and my daughter AND I'm hoping she sees this as a positive thing and that gets reflected on to me AND she sees how I value family.

Oof, and you were on a roll. "I'm hoping she sees.. how I value family" - Expectations and nicing her back.

"I'm willing to do it because I care about the connection between her mom and my daughter " - Your connection to your D is at least as important and arguably more-so. This puts others on a pedestal.

Letting your ex take your D away for months is very questionable imho.

Now my ex is having a birthday party with her friends who are flying here next week - my ex invited me.....
1- I'm torn whether to go or not....
2- I go and I was thinking of having my own party for our daughter later in the day and whether I should invite her and her friends
3- I don't go.....

Will your D2 be sad if she has a party and cake and presents with mom and her friends.. then party and cake and presents with dad and his friends? Could being together confuse D2? There's more than one way to handle this. I'd probably have a separate party since you described it as the ex and her friends. I'd do a combined party if she invited D2's friends, but then, I'd ensure to alternate who does this each year.
