Girlfriend says 'something is missing'
First her background, because I think it's important. We're both 30. She was with a guy for 2 years and she believed they would get married. He left suddenly and without much explanation. We met 3 months later and started dating soon after.
We dated for 4 months the first time around. Things were going great, but we just moved way too quickly. She had taken me on a getaway for my birthday. I had planned a trip to Europe for us over new years. She broke up with me in December after dating 4 months. She said that I was the most amazing person and perfect boyfriend that anyone could ask for. But she felt that something was missing.
So I did NC, I started dating other people, and low and behold, we got back together. Again, things were great for about a month. Her parents loooove me. We have a great time when we're hanging out. But I think we may chat too much online, see each other too much, etc. I think we just naturally have a tendency for some reason to worry about the future and what everything means in a grand context. We booked another trip, which we were super excited about (her idea)... Then 4 days later she again drops the hammer on me and says she feels like 'something is missing', a spark isn't there for her. This is 4 days after telling me 'I really really like you", sending me hearts and xo's etc. Well, the truth is I know she does -sometimes- feel the spark she's talking about. She mentioned that she fears getting a divorce one day.
I honestly think the root cause of this is her previous relationship and that she's constantly worrying that 'something is missing' because she's deeply afraid of being hurt again. But she says I'm the perfect boyfriend, physically, emotionally, etc. I'm by no means desperate, I have a lot going for me and beautiful women waiting in the wings for this relationship to not work. But I don't want to give up on her. I do love her and one day I want to marry her.
She's naturally a worrier. And she listens very keenly to what her friends tell her. I fear they're going to tell her to end it if she has these 'feelings'. But what I think her friends and others don't understand is the root of these fears that 'something is missing' have to do with her not wanting to feel vulnerable. Because the pattern has been, now twice, when we get too close too fast she pulls away.
So what should I do?
