vent !!!

I just want to vent out a little without giving too much info cause i feel no one cares lol but here goes i was with my ex for 7 years we tried getting pregnant never happened. we broke up 6 months ago started dating this guy for a few months thought everything was going well then it didn’t broke up and boom i’m pregnant! I can’t describe how happy I am that I’m going to be a mom , turning 26 next month ! but the dad hasn’t been here for me i told him and he was like it’s too soon to know and is it even mine ? he just texts me whenever he can and ask if i’m “ok”? never said what was gonna happen or what . i was upfront with him and told him i didn’t wanna get back just cause the fact that we’re having a baby together i told him he can be more than welcome to take a dna test after i give birth bc I HAVENT been with no one else but he’s like i’m so happy ima be a dad and then he’s like well i want to make sure it’s mine . so i feel i have been stressing a lot bc of him being in and out of my life and he’s tried calling me yesterday and the day before that . texted me once saying “sorry i called i just wanted to see how you’re doing .night.” i feel he still wants me to go after him and idk . haven’t reached back to him bc i feel it’ll lead to an argument and i will be stressing. i hope im not wrong with the decision i’m taking , my first appointment is on april 30th not sure he’s gonna show up. I guess I’ll end up being a single mom after all ...
