I feel like she was only my friend for my infertility

We both struggled with TTC, she did get pregnant though with medical assistance but my issue is a bit more complicated and it's not exactly clear why we can't conceive as yet. We met a couple of years ago.

Her child was born in October and I haven't met her as yet. I normally give people a month or so to settle with their new baby before visiting (I know everyone wants to visit ASAP but I feel it's important for the parents to have a bit of alone time with their new baby first). She also complained that she had family staying indefinitely and she didn't feel like having so many people away so I kept my distance too.

Then in December I went through a depressive stage and eventually forced myself to speak to people after about three weeks (I was diagnosed with depression as a teen, and have just kind of dealt with it).

I got invited to her ladies night in January/ February (can't exactly remember when) and we had a really nice time.

Then were making plans for me to meet her daughter, then a few days before the lunch we were supposed to have her daughter got admitted to a long term stay in hospital. I obviously asked about her every day, asked if there was anything I could do, etc.

Her daughter got discharged a few days before we went into lockdown in March. It was only last week it was announced we may visit people again (literally five months of not being allowed to visit people in their homes). We are allowed to visit each other at restaurants and about a month or so ago we did have lunch, me and her. Because of her child's prior medical issue I didn't want to expose her to whatever germs might be around.

We invited them for dinner at a restaurant about three weeks ago, but had to cancel as my mom was tested for COVID19 and was waiting on her results (I had seen my mom over the weekend). I told her the day before the dinner and she informed me then that her family member who was going to look after her child went on holiday for a few weeks so she was going to cancel anyway. And it's like that's fine but when we're you going to tell me?

We literally haven't spoken since. I am the one doing 90% of the conversation initiation. I will send a meme her and there, ask how she's doing how's baby, etc. and the conversation will last like three or four messages then die out. She's not initialed any conversation since her ladies night and I feel like it's because the only thing we really had in common was our infertility.

Should I just leave the friendship?
