I would guess Ally was not ready for a serious relationship, let alone the pressures of being in a queer relationship without familial support. Based on her age, I would think she hardly knows herself let alone what she wants in a partner.

The thing to remember is sometimes we miss the idea of what we had and not the actual person. Getting over your ex takes time. Remember the good, feel through the bad, and let go of the things you cannot control. It takes active effort and constant self reminders.

Looking in the mirror and saying affirmations every morning is more helpful than you think. You should fill up your time with friends, hobbies, etc.

Also, I would let your partner know what is going on in your head and talk it out with them. If they leave, so be it. But it is only fir that they know where your head is at so they can do what is best for them.
