I feel lost

So I’ve been with my boyfriend for almost 5 years. I got pregnant at 20 ( 1 month into dating) We have 2 kids together. He’s a very great dad and great partner. Over the fast years, I’ve started to lose feelings and connection towards him. I’m not going to lie but when I first started dating him, I was head over heels for him. We took a 1 week break and I’m

not going to lie I was bawling my eyes out but on day 2 I felt so much better. And then we got back together because I felt bad and especially for our kiddos ( who is 2 and 3). Because they kept asking where their dad was. I felt happier being single. I feel trapped. I’m going to be 25 this year and he’ll be 26.

(Yes, I’ve has the talk with him before and he’s like I didn’t do anything wrong.) I guess feelings changes.
