Imperfect friend

Hey There Imperfect Mums
More of a rant than a question

I'm an imperfect mum, but I'm also an imperfect friend. It all usually comes hand in hand doesn't it.

3 months ago I met a guy, I'm a single mum of 3 adorable kids with plenty of family support. My new Boyfriend comes in on weekends due to his work. My kids go to their dads on the weekend which means I can take my relationship slowly and get to know the man before he meets the kids. I have one or two close friends who I have all the time in the world for but usually we see each other during the week when the kids are at school and daycare. Over the weekend just past my new boyfriend and I went to have dinner and watch a band at one of our local pubs, - my friend messaged me to see if I was still going and I replied that I was. She gave no request for a lift or the need of a lift and I had already mentioned that we were taxing it to the venue as neither of us would be drinking or driving and we were planning on a massive night, all she had to do was ask and we could have diverted the taxi to her address if she needed us to but were on the other side of town to her and she lives closer to the venue then we do. Her taxi would have cost $10 Max from her house. Her dad (he's pretty cool) was also at the venue we were going to and she could have caught a lift with him. She is quite the introvert but she can also be an extrovert in the right situation. She said she didn't want to go if she didn't know anyone else there. She would have had a possi of friends if only she took the time to ask if they'd be there. Today she has been making snide remarks on her. she's making comments on Facey about how she didn't get there and not wanting to walk to the venue on her own in the dark and about people's integrity. When we go out we usually walk in the dark to our destination and then walk home again it's not far and it's an easy walk. Since I have gotten a boyfriend she seems to have taken it badly. I invited her to my 30th and she didn't come. I've also invited her to do other things. My relationship is new we are still in the honeymoon phase, my boyfriend and I do only get 48 hours a week together during the week so we like to have dinner and a little time with each other while we can before we head out and socialise with mates. It works for us. We do go out as a couple and we either hang together or wander off to be with friends but we always gravitate back to each other it's how we work. I realise my friend is possibly upset about me finding a boyfriend and that she is still single and probably feeling it. Maybe a little jealous. I really want her to be happy for us. I think she is great. I am still my own person and I still have a lot of fun, there's no way she's be a third wheel in any situation because there is always someone else around that she knows and it used to be me that would be left at the table while she went and talked to her other friends. I feel as if she is targeting me for finally getting my shit together and because I am completely happy and enjoying my little life. I also want her to be happy. I feel if you don't put yourself out there then you won't get any where. Did I do the wrong things by not suggesting she take a taxi with us, or letting her hang with us before we went. She was also invited to a group thing on Saturday by my other close mate which she didn't come to either.
