I've been running for about a year and dream of getting under 60 mins for 10k. PB 77 mins so far - aiming for under 70 as a first step.
I've run in 4 races so far and loved 3 of them. The last one was 10 miles - the longest I've ever run, and I came second to last, but it was such a great atmosphere I really didn't care. Chose carefully, and the race will be fun. I'm sure people will give suggestions if you say where you are based.
The other thing which helped me is my jogging group. Not a serious running clubwith structured training, but a Run England organised thing. But it sounds like the park run might serve the same purpose as this for you.
I've started to add temp and speed session in, as the variety stops me getting bored. I have come up with a training plan using the smart coach, but use this as a guide. For example last week I was by the sea where there was a jetty out with amazing views and few people on it. So I ran intervals on it - sprinting out and running back. I've also started to go to the local track which I find suprisingly enjoyable. This works well when running with my partner, who is faster than me, as he can just do more intervals.
I'm not sure what to add to the comments about your husband's attitude. It is probably worth chatting to him and finding out where the comments are coming from. He might not realise he's hurting you, or he might be wishing he had a similar hobby himself.
