Boyfriend gone off sex

Ash
Hey lady's..
If you follow me you would know Im very paranoid in my relationship..
My boyfriend has gone off sex, it's been nearly 2 months now, we didn't have sex a while because I got the coil fitted so it must have been around 3/4 weeks, we went away to Liverpool for the night had sex and ever since then we haven't had sex... Is it ME?! has he gone off me?! Am I doing something wrong? 2/3 months down the line in getting a bit scared and emotional... I asked him if he felt frustrated at any time and he said "no, I just don't feel that I want it, it's been so long" 🙁🙁 helppppp
