Single First Time Mom

So just needed to vent. Being a single Mom is ruff and seems like everyone around me has help wail I'm out here on my own. My son's father left us right after he turned 3 months old cheated on me and got his new girlfriend pregnant and decided to walk out of his son's like after only a month of actually living with us and being with his son. Sucks so much. Then now with a new guy I thought liked me but he's showing signs of blowing me off repeatedly even though he's the one always asking to hang out and be togther then he just goes m.i.a. I always forgave my son's father and just let everything go and I regret it so kuch looking back at it so it's hard in this new relationship for me to not want to just run even though it's only been 3 months. I just feel like you shouldn't date somone who you knows been broken when it comes to trust then make up excuses as to why you can't make it legitimate or not it's a hard pill to swallow thinking you're going to see somone you've grown to care about then they just continuously ghost on you. Idk everything about everything scares me for me and my son... I don't want 2 men to have walked out on him and his life I'd feel so guilty if he got attached to my new guy then he started this ghosting me up again... Ugh... 🙄😔
