Oh, of course, you will! Love doesn't stop because we have babies on our own. I was a single mother to DC1 who turns 18 in February. I went on to marry and have two more children. That's coming up on 11 years ago. It took time for me because, to be honest, I just wasn't interested in a relationship until DS was about 4-5 years old. I'd been so burnt out by my ex, who is not a bad guy but he is a terrible father. He's just never 'shown up'. He was at the birth and even then, it was like, "please, just go do whatever it is you're sooo missing out on because clearly, the birth of your son is not at the apex of your life's experiences." He still hasn't found whatever it is he's looking for.
You just learn your road ahead as a new mother, be guided by your loving heart, be patient with yourself, above all, and you'll find that raising a son to be the man you envision him to be will happen. I couldn't be more proud of my son. We didn't have a pot to piss in and I worked hard with little financial reward, but to be honest, those were incredibly happy years. Of course I was very lonely. I so wanted to find love but I sure wasn't going to revisit any relationship resembling what I'd had with his father. I was too nervous to get love wrong again. You will absolutely know when it's right.
They're definitely a lot of guys out there who think, as a single mum, their crumbs of loving will be enough to sustain you, that you'll be grateful for anything, any kind of attention, guys who think they don't have to make much of an effort because you're just so damn grateful for their part-time affection. Fuck them. They're in the same club as your ex. There are even more men out there who are kind, strong, and loving, men who will love your son as their own, men who will respect you! Respect is what you want. Love functions beautifully when respect is intact. But don't rush these things. Love finds its way to you when it's good and ready... when you least expect it, my colleague used to say to me. How right she was.
Try not to allow your ex to bring drama and toxicity to your life at any point, but especially now. You need to be strong for your baby and for you.
