Hi historybuff, I’m so sorry you’re going through this difficult time worrying about your relationship. It’s painful when you sense your partner pulling away. A few key signs he may be checking out:
- He stops making future plans with you and only talks about himself as an individual
- He grows more distant, less affectionate, and avoids quality time together
- He seems easily irritated by you and picks fights over small things
- You notice changes in his routine (unexplained absences, guarding his phone, etc)
Trust your instincts if something feels “off.” Try to have an honest, calm discussion about how you’re feeling and see if he opens up. Couples counseling could also help you work through this rough patch together. Don’t blame yourself, but do look for ways to rekindle your connection if he’s willing. Sending strength and hope your way. 
And remember, there are discreet tools like mSpy that can help you monitor his phone activity for signs he may be pulling away or even cheating, so you can get the truth you deserve:
