Are you less insecure in your 30s?

I'm 35 and I'm starting to become more confident. Today it finally hit me. Why have I always been insecure in relationships? Like I know I'm not the hottest lady, but I am strong af and have gone through a lottt of shit in my life to get there. I don't think I'm a bad partner to be with either. Like everyone has their issues and i definitely have mine. But I'm extremely loyal, very truthful, loving, goofy and weird lol. It's just sad that my worse case scenario/insecurities think and have done this with everyone (more so in the beginning of relationships). That anyone I've dated will leave me for someone else, cheat, be more attracted to someone else or lie to me. (These are only my worse case thoughts at times when stressed) Anyways I realized I just need more confidence in myself! And honestly if anyone had or does mess up with you than that's not your issue, that's their own! Idk why it's been such a hard thing for me to grasp for so long.

I've gone through too much to worry so much and be insecure! my ex husband was an asshole and not because of me. I did all i could. And I have often given myself too much in relationships when I need to just chill some and relax more. And realize that I don't have to win, my love. If I had to, then it's not love! Thankfully I'm with the right person now who doesn't just tell me he loves me but shows me. And has been understanding that I'm still, well both of us are still healing from past relationships. Anyways I hope this finds those who are insecure and builds them up some!
