Chelsea being jealous is OK it shows affection and love… but shouldn’t overdo it..
you both have spent more then a year together.. which is very positive point.. and u must have so many good and happy memories with him.. the quality time you spent together.. try to remember all that good time you had whenever you feel negative about him.. try to replace your negative thoughts to positive ones
there are things you can control and there are you cant, past you cant control it.. and remember it was never your fault .. and slowly let them go …
let the past go, let the fears go, let the worries go and breathe
Bless you
