I think I met someone

I meant somebody about a week ago and he Seems to be a nice guy. I’m starting to like him but I want to find out more about him. I think if I’m not mistaken he said he was a veteran but I’m not really sure he had knee surgery done a while back and he’s been trying to get on disability. But, here’s the kicker he doesn’t have a home. I know it matters to some people but it doesn’t matter to me. The thing is that when my ex husband died I thought that was it I thought there was nobody else out there for me because my ex-husband was my soulmate and I was planning on someday getting back with him but he had passed away before I had the chance. So, when he passed away a big part of my heart passed away with him and I and when he died I had built a wall around my heart to make sure that I wouldn’t feel that way again and get hurt. But, somehow this guy had chipped away at this wall that I have built around my heart in a very short time. I don’t know what it is about this guy but he makes me feel like I’m a teenager again even though I’m 51 years old. I don’t know if I should give him a chance or walk away. So I’m looking for advice from my friends on here what do you all say? Should I give him a chance or just walk away? Yes or no my friend what do you think? Thank you my friends and God bless you all.
