For 5 years, 5 whole years you had what you thought a good, healthy relationship.

3 months into living together, and things went downhill at full speed.

You said it yourself, "great to really bad"......

Now I don't know what you've built for the 5 years before the relationship (as you mention 10 in the post above but mention being together since age 25) but I ask you this;

Is it worth going down this rabbit (wormhole)hole that moving in together has opened up?

Also, dependency issues are a right b1tch, I get it, but what price are you willing to pay for your comfort zone?

You're already paying in self-esteem, insecurity, doubt, pain, sadness...
All of this in just 3 months, soon self-respect, trust and dignity will follow, so at which point will you decide the cost is too high?

Have you set a limit, do you have a limit?

No, please don't think you have to answer on this thread, just something for you to think about.

PS. This is why even though I come from a staunch Christian background, I am definitely for moving in together first. You never quite know someone until you live with them. At least this way, people know exactly what they're signing up for, and if they sign up regardless....
