Guys, My sister is a single mom, is there hope for her?

Over the weekend we had a family lunch and my sister who is a single mom, came with my niece. We haven't seen her in about a year so it was nice. I took the opportunity to ask her how things were going. She seems pretty happy raising my Niece on her own but I asked her if she misses being in a relationship and she said " Well yes, all the time but men nowadays don't want single moms, so Ill have to accept my fate"
I feel horrible for her because the father turned to substance abuse when she fell pregnant and it was not safe to raise her child in that home. So now she's alone and has been for years. she's gone on dates but says guys get scared when she mentions she has a kid.

I dont want her alone forever and she's an amazing mom and person...

Are guys really against dating single moms or is it just a specific age group that doesn't accept someone else's kid?
