How to get into Little Space

[LittleKitty666]

After my last relationship I haven't been able to go into my little space. I think it's cause in the relationship when I had to talk to them about something important to benefit the relationship they would automatically put me into either my little space or my pup space and I would then be unable to talk about it. It was mainly my little space they would do this with. I have tried to go into it but it made me feel really uncomfortable and I've been mainly going into a pup space without anything triggering it. Any ideas on how to ease into going little or going into the space completely?
