Why did my ex move on so fast, we have only been broken up for 2 weeks?

They think that just because they did the emotional checking out while still being with you, they don’t need to work on healing and processing once they left for good.

Do everything to avoid solitude as much as possible.

And the way this manifests is that they:

Get into relationships before they’re able to emotionally commit to someone other than their ex.

It‘s also a very common reason for breakups — people just don’t take the time and space anymore to rediscover life without their ex, to heal in solitude for a couple of months, to mentally and emotionally adapt and adjust to the single-lifestyle (life when in a relationship is very different from life when single) but jump straight into a rebound and thus, they carry all their past emotional baggage from previous relationships into their new ones.

On some level expect their new man/woman to make up for the wrongdoings of their ex.

How come I can't stay sober?

Leave things unclear, open-ended and complicated with their ex where it constantly interferes with new relationships.

Constantly compare their current men/women to their exes.

More often than not this happens because people tend to overestimate how fast they can move on and process a breakup and underestimate the work, power and awareness this really takes.

Why do liberals think same-sex marriage is alright? The Bible makes it very clear that it's not alright to be gay, why can't liberals understand that?
