This is a textbook toxic relationship. Inconsistent behavior, love bombing, hot and cold, actions don't align with words, the list goes on. Another big reason such relationships are so damaging is because they mess up your brain chemistry. You literally become chemically addicted to the rollercoaster of it, and are not actually thinking clearly. When it's bad, the adrenaline and stress hormones flood you, but when it gets good again, the relief and happy chemicals flood your brain and you're addicted to getting that next fix. It's a constant loop. That's also why no contact is important, to break the loop.
That being said, it's normal that you're in shambles right now. Your nervous system is dysregulated. Your mind and body is a mess, your confidence is affected, and it's okay.
In my opinion, you should absolutely not be dating right now. You're in no mental or physical state to date around. You're not in a balanced, secure state, and as such you'll inevitably make decisions coming from vulnerability, from survival mode, from a desperate need-based mindset, and a dysregulated nervous system which is just looking for relief anywhere it gets. It's grounds to get exploited by the wrong people and a whole load of other messy situations that do not benefit you.
Sit yourself down and just focus on yourself. Breathe. Meditate. Journal and pray. Go to the gym, go for a run. Remember the things that bring you joy and peace, and focus on them. Slowly, you'll return back to yourself. And when your nervous sytem feels calm again, and you're paying attention to the glimmers around you, life feels lighter and you breathe in ease again, then, you might be ready to date again.
PS: For all the ladies out there, please listen to me when I say situationships are a scam. Unless you're the kind of person who can stay 100% detached with multiple partners for a long term, stay far away as possible from them. Men reap all the benefits, meanwhile you reap none (or a very shallow, temporary one) yet take all the risks. You're doing yourself a disservice and it's only in the detriment of your mental & emotional wellbeing, not to mention spiritual. All those people you give access to your energy and viceversa.... so if you play around with a lot of lazy, directionless, depressed people, you're literally absorbing all that energy into your own.
Be more discerning and selective, your feminine energy is so incredibly powerful and sacred, and should be treated as such.
