It’s one thing to ask for a break to take care of business, but it’s another thing to string you along indefinitely, which is what your girlfriend is doing. 😳
It sounds like she most definitely does have a lot on her plate: a child, work, school and having just bought a new house, she sounds swamped. That said, this is a time when some couples get even closer, so her pulling away indefinitely is not a good sign.
You need some clarity from her, and it’s time for you to find out what she has in mind. If she can’t be more specific about your relationship, then sadly, I think it’s time for you to move on and find someone who is available, because she is showing you very clearly right now that she’s just not available.
I hope that helps.
