I (29m) was dating a 26F for 4 months and it was completely magical. We went on the best dates imaginable and it felt so natural. I had the mindset of going with the flow and due to past relationship trauma I kept her at arms length emotionally and I take accountability for that. On Sunday I received a breakup text ending the relationship and she said doesn't see it going somewhere long term. This is several days after her bringing up going on vacation together, cooking together and having sex. It felt out of the blue. We also recently went on our first trip together to a concert 4 hours away and stayed the night. We had such an incredible time.

Is my lack of emotional intimacy causing this breakup and ones in the past? We never had a "Where is this going?" or "Exclusive" conversation
