GF Goes silent for two months then can’t believe I met someone else

Me and my GF had a bad encounter New Years Eve. It was my fault as I was drinking a bit much and voiced my concerns. We parted for a month and talked through it like adults and we both agreed that we need to communicate versus letting things bottle up. Fast forward to early May. We went away to visit my friends out in the Midwest. As we were constantly busy and rarely had alone time I was disappointed when she would wake in the am (as this was our only chance for some one in one time) and immediately go upstairs.
Well on way back from airport when we were headed home I voiced my needs in a non-accusatory way and just let her know I was disappointed. I didn’t hear from her for 5 days and that was because I reached out. She said I have had two big losses in the last two years (wife and Mom) and that I need time to get through the grieving process. Then a week ago she texts me basically just saying Happy 4th. This is 7 weeks after her last text. Then she starts texting me more regularly and asking me to go to do something. I told her I met someone organically and don’t want to multi-date. She couldn’t believe it as she said I am her happy place. If I am her happy place why would she wait 7 weeks to text? She said she never said she was done seeing me. It makes me question my sanity.
