New member here - wanted to talk about T1D and relationships

Hi everyone, I've had T1D since I was 5 years old and I'm 30 now so been living with it for a long time. I was in a relationship for 9 years with a guy and it was long distance but we made it work over the years. We did have plans for living together but then the pandemic happened and plans changed. During the whole pandemic I rarely went outside and if I did I always protected myself. I was lucky that I never got the virus until early this year in January. After years of being locked up and isolated I did get it from someone close to me and I also got severe flu and sinus infection. I became very ill and the whole time I was sick my boyfriend wasn't there for me. He didn't respond to my calls, texts, nothing. He kinda ghosted me for a while when I told him I was really sick and feeling out of it. A month passed and he finally messaged me to say he didn't want to be with me anymore. He texted me out of the blue one day and simply said he couldn't deal with all my sickness and didn't want to talk to me anymore. Obviously I was completely shocked and heartbroken and I just couldn't believe it. This relationship we had for 9 years was thrown away and treated like it was nothing. What upset me and hurt me the most was the reason he gave for the sudden break-up. He said it was my chronic illness that made him realize he didn't want to be with me anymore. In the past I never had serious relationships, I did have boyfriends but they were all short term and didn't last due to infidelity and lies on their part. Long story short I wanted to come here and ask: is it normal for people to not want to be in relationships with T1D? Like is it okay for a guy to say he doesn't want to be with a girl because she's a diabetic? I don't have any friends to ask for support, I've been a loner all my life and have struggled in relationships. I do have other health problems besides my T1D, too many to list here but I have managed my T1D all my life and I consider myself an independent person because I have always felt I am a burden to my family and I don't want a guy to feel like that in a relationship with me. It's been 6 months since this awful break-up and I still am healing but trying to have hope that maybe someday I'll meet the right guy but at this point in my life I feel like I'll always be single forever. I've accepted that truth and am learning to embrace being single and just been focusing on myself and my deteriorating health. Thank you to anyone who read all this and appreciate any responses. Just seems heartless and cruel for a guy to break-up with a girl because of her health problems. Need to know if that's normal I guess.
