Relationship Insecurity

So like I posted on here couple of months ago I broke up with my BF... which apparently he sorta cheated on me... Well I like to insist that it's cheating although he never really agreed to commit to me.. But yea he cheated, cos he hid it from me.. Anyways... he got into a relationship with this girl very quickly (they are BF-GF immediately) and it made me really frickin mad and crazy for a while.. maybe about 1-2 months.

Well thanks to my current love interest, I moved on from my Ex and we are actually friends now. We still talk pretty frequently and I have almost zero negative emotions about it. And guess what? The GF is now sooooo damn insecure about me. And I'm just lalalalalala and act very chill about the whole thing (as long as my Ex still talks to me every now and then, as a friend).

Honestly if this girl wasn't a catalyst to our break-up, I would totally back off more than I do now, to respect their relationship. Cos I understand how intimidating it would be if I was with someone that still talks very frequently to their ex. And my ex is always very bad in giving an assurance in any romantic relationship he is in, BTW, so that is his fault. And yea frankly I enjoy this time, when I'm pretty much chill about our friendship (my ex and I) and he kept telling me about how stressful it is that they always argue about me. Girl, isn't karma a bitch?

Honestly again, if they ended up together for a long term relationship, that's fine too. At this point I don't want to go back with my ex anymore (he doesn't have anything to offer but love. Literally). I just feel kinda bad that he again ends up in that kind of dynamic. An insecure gf. I was one. But at least we were in a long distance relationship. This girl is actually there, living pretty close to him. Oh well... who cares now?

In the end of the day I learn more and more that insecurity in a relationship is inevitable. But there's nothing really you can do to make it better, other than to be chill and accept the reality, or leave. The more you nag about things that make you insecure, the more they (the guys) are turned off by it. If you're not okay with many things in the relationship and continuously feeling insecure, leave. Of course it's easier said than done... I'd know that better than anyone lol....

Dating... (have I had a post with this title before..?)

Ever since I broke up with Eric about 3 months ago, I've been involved in a dating saga.. Met 3 people and had a great time with the first two. The third one was a funny story but not sure if I wanna talk about that...

First guy I met was great on a paper. He's an engineer, 29 y.o., looks like he's pretty settled financially, oh... very good looking and great body, he is a surfer too - so you can imagine. Hmmm what else, oh he's a Catholic (wow!) and seems to have a nice family. Buttt... it failed lol. We had a great time the first time and then we were gonna meet up the 2nd time which he bailed on me twice! So the conclusion is, he might have a GF and a total douchebag...

Second guy is great... He's very good looking, tall (I only date guys 6' and taller lol), very sweet, very successful in his career, very attentive, and... very good at.... dudududuu.... so many things ;)
In fact I'm still seeing him.. But this wouldn't go anywhere, which I don't really wanna elaborate why.. In the end of the day he's really something and I'd probably remember our time together forever in my heart..

Third guy I met was a musician, played 6 instruments. Pretty good looking, pretty short to my liking (5'7") and very pretentious. Oh and he's a 90% vegan. Big no.... I loveeee food too much to date you dude. And so many other things I don't like about him...

We'll see how all of this dating saga go... ;)
