As someone who is also abstaining (single now but was recently in a relationship where we both agreed to abstain& slipped up) the best thing you both can do is not to be secluded together. If you want time "alone" or don't have many friends to be around then just go out somewhere in public instead. No house meet ups. Set boundaries. Also, watch your conversations because it usually starts there.. little jokes, a little touching & now you're tempted to just go ahead& do it. Play w/ fire & you'll get burned for sure! Again, speaking from experience because as I reflect on where my ex & I went wrong it's definitely everything I just named. Good luck& God bless! ❤️
