I 27M feel like my relationship with 24F is over, am I wrong?

Quick bit of context, we met over the internet, spoke for months and a few months after meeting we were expecting our child.

Fast forward 5 years, after a horrible birthing experience, she’s now full of anxiety and has a bad brain condition that pretty much keeps her bed bound.

Unfortunately because of her anxiety and the fact she’s bedbound I’ve been dealing with all the house chores as well as looking after our child (which in the beginning was probably the hardest experience of my life). As well as this she doesn’t get on with any of my family or friends (tbf my friends weren’t the greatest people) so I hardly get to see any of them and when I do, it’s usually my mother who helps us out with collecting our shopping or when she’s taking our son to the park for an hour or so. I should also mention, as this is a common complaints I’ve had with her, I don’t get out the house much due to her anxiety, I could probably count on one hand the amount of times I’ve been out the house this year. We’ve also not made any sexual contact (including kissing) since the beginning of this year.

I feel like such an asshole as she has nobody around her to help, she cut contact with her abusive mother (before we met) and moved in with her father, who is also having his own problems.

I feel selfish for wanting to leave, but I don’t think there’s any spark between us anymore. She’s passionate about things that I don’t really care that much for, the same way she is with things I’m passionate about. We really rushed into this and I’ve been feeling like my life is pretty much over ever since.

I think having a child together is the hardest part but at the same time, I want the best for him. I’ve really got a strong bond with him as it has kinda felt like it’s just me and him most times. He’s never really came into contact with anyone his own age and the most excitement he’s had is going to the local park with his grandmother for an hour. I want the best for him and don’t feel like he’s really getting that in our position.

TL;DR: Relationship has been downhill since birth of our child. We’ve had no sexual contact since the beginning of the year. She has no family to help her out and has pushed my friends and family away. Am I wrong for wanting to leave?
